Hello all,I have 1721 point features, which I am combining into a single line using LineBuilder.Each node has a datetime stamp, and I want to populate the line with the attributes "start_date" and "end_date" drawn from the "date" attribute of the first and last point feature.In the LineBuilder I have ticked the parameter Generate List, so I have a list with 1721 elements.I can use the Attribute manager to create a new attribute "start_date" with a value of;@Value(points{0}.date)However, I fail to do the equivalent for the last element in the list.@Value(points{-1}.date) is not accepted by the Text editor or the List Element Selection: points{}.dateI thought I might solve it by using ListElementCounter, which does create a new attribute with a value of 1721, but again the List Element Selection: does not accept an attribute value as an input. 

Hello therewe have data structured this way  PlaceAttr1Attr2P1213P2104 and we want to convert it to this structure PlaceAttrP1attr121P2attr110P1attr23 P2attr24 Any idea, pleaseThanks

Hi,I created some user parameters and want to set their values programmatically some time later (when some data is processed). Is this possible? Or I must set their values initially?

I have a feature writer transformer that exports to .csv. For the dataset parameter and CSV File Name I have an attribute "_dirpath" and "_outputName" that are both dynamical created based on the input and the time.The problem is I want User Attributes to be set to "Automatic" but at the same time there are certain generated attributes that I don't want showing up in the output.I can use an "Attribute Remover" on most of them with the exception of "_dirpath" and "_outputName" as I need them to tell the feature writer where to write the file to. How do I get out of this catch-22 of having "_dirpath" and "_outputName" available to the feature writer but NOT outputting to the file?I tried using "VariableSetter" and "VariableRetriever" to assign the attribute to a Private User param but this does not work as I later read that "FME configures user parameters before starting the translation, and their values cannot be changed in the workflow later." Having a global va

In workspace 1 (WS1) the "_dirPath" and "_outputName" is derived from the input and a timestamp. For example: Input: C:\Temp\MyFile.csvOutput: C:\Temp\MyFile_2019-8-22.csvThese values are then passed into a custom transformer (WS2) so that  _dirPath and _outputName show up as User Parameters.This is done because :Answer by takashi · Feb 14, 2018 at 02:56 PMFME configures user parameters before starting the translation, and their values cannot be    changed in the workflow later. SourceIn WS2 I have a Feature Writer that exports to csv. The Feature Readers Dataset is set to, $(_DIRPATH) ie. the user parameter that is set from "_dirpath" in WS1 and the CSV file name is set to $(_OUTPUTNAME).Now, this all works fine. The problem is I want the feature writer to have it's User Attributes set to "Automatic". Yet, at the same time I don't want the attributes of "_dirPath" and "_outputName" showing

Hi, I have an urgent question.I have a point file. Each point has a rank number and a circle size.Basically, what I am trying to do is to:1: Find the point with the highest rank and add it to the selected list.2: Find the next point with second-highest rank & draw a circle (using circle size), the point is selected and added to the list if there are no selected points (from 1) from the list inside the circle.3: Find the next point with third-highest rank & draw a circle (using circle size), the point is selected and added to the list if there are no selected points (from 1 & 2) from the list inside the circle.4: Repeat the process until no points left.Thank you so much in advance.

I have to sample a large area with high resolution: A country with a resolution of 1 Meter. I will use points for this which eventually will be written to a database.I will have to split up the calculation, e.g. 50 by 50 km which would result in 2.5 billion points per run.Can FME handle this? Or would it be better to split the calculations to smaller parts?The computer has 64 GB of RAM.

For some reason I can not get this to work, and its driving me nuts. I am using a File & Directories reader in conjunction with a Workspace runner but am unable to get the writer to function correctly. The data is a bunch of shape files (point, line, polygon). The usual method of using fme_feature_type with a dynamic schema does not seem to work. If I use path_rootname for the outgoing file names it does save the files, but they are empty. Any ideas? 

When running my workbench locally, there are no issues/errors. However, when I publish to the server and the workbench gets triggered by an automation, I get the following error in my log:The clause 'TEST @Value(fme_rejection_code) != FEATURE_TABLE_SHIM_SUPPORT Yes' within 'FACTORY_DEF * TestFactory FACTORY_NAME Date_Converter_Rejector INPUT FEATURE_TYPE ___TOREJECTOR___ TEST @Value(fme_rejection_code) != FEATURE_TABLE_SHIM_SUPPORT Yes OUTPUT FAILED FEATURE_TYPE Date_Converter_OUTPUT @RenameAttributes(FME_STRICT,fme_rejection_code,___fme_rejection_code___)' is incorrect. TEST must look like: TEST <value> <operator> <value> [ENCODED]Edit:Just fyi, may have something to do with it: The DateTimeConverter is followed by a matcher. Any help would be appreciated!Thanks.

Today I ran into a problem executing workspaces containing multiple versions of a custom transformer, which has parallel processing 'turned on'. I was wondering if someone has some thoughts on the matter I found.I am using FME 2016.1 build 16494.With all the instances of the transformer embedded the workspace runs fine, and reacts to changes in the parallel processing level (and the amount of groups the data is split into) quite like one would expect.When I have the same custom transformers 'linked', the whole thing crashes and / or does not function at all.As soon as the linked transformer is read, it requests for the amount of threads regulated by the default value of the Parallel Processing Level of the Public parameter I use to set the level. The value of the parameter in the workspace from which the transformer is set does not seem to affect this initialisation-value.When set to moderate it means every transformer requests four

Dear FME Community,since recently i have trouble with FME on parallel processing. When the first feature enters any custom transformer i get an FME appcrash. Also, I get different error messages on the same workbench, which is very unusual. -------------------------------------------- Error_msg begin ------------------------------------------------------------Error 1(most frequently):|WARN |0arning: not all FMESessions that were created were destroyed before shutdown.

In my company we have installed the FME Server on a server only accessible from inside the intranet (so no internet connection). I want to publish some workspaces to colleagues without the need of signing in, so I built a simple html file with a JavaScript form in it, based on the FME Server playground examples. My goal was to place a html-file accessible for all relevant colleagues, they can open it in their browser and submit a job. Unfortunately it doesn't work because of the CORS policy, which throws an error.Is there a simple way (maybe another?) for "publishing" workspaces inside a custom environment (like an own HTML file) in local networks without the need of changing the CORS preferences? 

In pre 2019 versions of FME I often used a python scripted parameter to generate a timestamp which I used in the filename of a File Geodatabase.All I used was:import datetimereturn datetime.datetime.now().strftime("%Y-%m-%d %H-%M-%S")Now I can't get it to work anymore. The moment I add the parameter the workbench is done:2019-08-19 11:26:35|   2.1|  0.0|FATAL |GEODATABASE_FILE writer: An unknown exception occurredI suspect it has something to do with the deprecation of python 2.6? What configuration do I need to set to get this to work?My Python skills are nonexistent, so it might be something obvious but I can't find what I'm doing wrong.

Hi, I have published a workspace on FME Cloud (2019) where the user can submit parameters such as name, date of birth and comments (using this tutorial below adjusted this slightly to incorporate the new advanced 'webhooks' functionality) and a prettier html form. https://knowledge.safe.com/articles/1295/send-source-data-to-fme-server-with-http-post.htmlThe target URL is as follows: https://<fmeServerInstance>/fmedatastreaming/test/test.fmw?username=bruce&dob=20190101&comments=playstation<&tokenid>Based upon the sensitivity of the information being passed (username, date of birth, status), is it possible to customise the respons

I have a ListBasedFeatureMerger to merge requestors that have IDs that potentially match the ID of the supplier features.I understand that a list can be generated if there is no complete match with all IDs of the requestor list.In my case, the generated list "_all_matches" appears in the result on the UnmergedRequestor port (see screenshot 2, it has two entries).However, I cannot access these attributes with any transformer.How can I get access to them?   

For some reason the default text size for annotations in any FME workbench has changed, and I can't find a way to adjust it back. Based on this link it should be under Tools>FME Options>Appearance, but not on 2018.0, it seems... Currently the text is huge (up five notches from the default size):

Is there a best way to automate what a MySQL Reader and Writer should use based on a specific file name? For example if file name = foo.txtUse the reader/writer DB connection for fooDB.If file name = fooBar.txtUse the reader/writer DB connection for fooBarDB I know that User Params along with a Filter in the automation may make this possible, but I don't know if that's the best route to go. I would also like to refrain from having multiples of the same workflow for thier respective DB connections. Thanks in advanced!

Hi, From a running workspace i would like to write the userid,starttime, endtime, and the filename of the workspace into a metadatafile. Starttime an Endtime is possible with datetimstamper but it is not accurate. Does someone know the solution?Kind regard Kees  

I've started have a problem where my transformers jump around in the work space. They seem to be snapping to the upper right corner. This tends to happen when I connect it to the output port of another transformer or to an existing connection line. Occasionally it will happen after I hit OK after updating the transformer parameters. I have verified that the grid and guides are both unchecked. I'm on 2016.1. Has anyone else seen this and found a setting to prevent it from happening? I can be very inconvenient when working with a large workspace.

How can I define a for loop, that count the average one after an other point. I sorted the point list, so now they are in ascending numeric order, and I want to calculate get a values that comes from the average of the points . For example: the fifth elements average is counted from the first five data, the sixth is from the 1,2,3,4,5,6th element?

I'm using WorkspaceRunner to run several workspaces. Then a FeatureReader reads a folder where the output of those workspaces would go. I need to list the output in the email and also attach them to the email. If I just attach the featureReader to the Emailer, I get multiple emails. If I aggregate the files as a concatenated list, the emailer doesn't know how to parse the string to attach the files. I need some help.

I need to read a GeoJson from an URL. One of the attributes of the call is the current time that I could get using the "Date/Time Functions" on Text Editor, however those functions are note available in the reader. I tried to use a FeatureReader where I can set the current time properly but then I don't have the "Network Authentication" options under parameters.  Any clue on how to set the reader source GeoJSON URL dynamicaly?

Hi I have a number of features, each with a list of dates which I obtained using PointOnAreaOverlay.I would like to order the dates within the list. I am using PythonCaller to process the list and write to a separate table. Any suggestions?

Hello community,I have a folder with all .mdb files that I want to process independently. Therefore I am using a 'directory and file pathnames' reader together with a workspace runner. So every file is send to another workbench, where it will be processed.In this 'other' workbench I have a 'Microsoft Access' reader, with the 'Single Merged Feature Type' box switched on. When I select the table name myself it works all perfectly. However, here comes the trick. The table names that I am using are different for each incoming file. For example the table name for file 1 could be trees_abc, for file 2 monumental_trees_abc and for file 3 tree_export_abc.The table names have one thing in common. They contain the word tree and always end with _abc. This regular expression should catch all the possibilities: ^(\\w+|)tree\\w+_abc (so it has the word tree somewhere and always ends on _abc). Now I was wondering if I could implement this regula
