PointOnPointOverlayer stores duplicates in list, how to read from Pythoncaller?

Problem in short:I have a lot of points which some has identical coordinates. PointOnPointOverlayer does this for me and store the “twins” in a list name. Now I want to use a Pythoncaller to loop through the list of each feature and figure out if some or none of the twin attributes has a value that should update the the major feature. The problem is that I cant seem to reach the list variable created in PointOnPointOverlayer from the Pythoncaller. It seems to be exposed when running with feature cache and checking output from PointOnPointOverlayer. What’s the magic for reading the list, looping throug it and check the attribute values? Tried this example code from the PythonCaller just to see if I could reach the list but can’t see anything:

Aggregator removing projections?

Hello everyone,I am trying to write data into an SQL Database which contains multiple geometries (This is borehole location data containing the originaly measured location (point), a corrected location (point) an a borehole path (linestring)). After creating the geometries from fields and using a GeometryPropertySetter for each of these geometries I am using an Aggregator followed by a MultipleGeometrySetter-Transformer. This is working more or less as in 3 Geometries are in fact written into the database which then also contains 3 fields with SQL geometries as set by the 3 GeometryPropertySetters. But there seems to be a problem. Between setting the individual geometries and aggregation, all info on the previously set projections seems to be lost. Upon inspecting each individual GeometryPropertySetter all points are where they should be. Inspecting the following aggregator shows all points off bounds somewhere. It is my understanding that the aggregator should simply collect the input

Reading DWG with 2 transformers

At this moment I received a DWG drawing with both Extended and Object data. To convert this data I first have to read with:Autodesk AutoCAD Civil 3Dthen read withAutodesk AutoCAD Map 3D Object Dataand merge all features on the autocad_entity_handle Am I doing something wrong or is this the only way to get both attributes?Is it possible build a transformer that uses both reading engines because I think that would make the reader faster than current.

DEM Raster Feature class to JPEG

Good morning,I am reading a DEM stored as a raster feature class in a gdb, clipping to an AOI and then writing to JPEG to be used in road design software.I can read and clip properly but having trouble writing to JPEG. I have gathered I need to set up bands differently but I have tried the rasterbandinterpretationcoercer and rasterbandadder and rasterinterpretationcoecer in various configurations/settings and can’t seem to get it to write a JPEG. Usual error is about the number or type of bands depending on how I set the coercers etc.DEM raster feature information Any suggestions would be welcome.Thank you so much,Corey

tester with wildcard for "only" any folder following

I have a test looking for many possible cases. one of the cases I want to find is Any folder inside of any folder that has some specific names. (BTW I am using directory and File Pathname reader to create a list) and then a tester to get all of the special cases.)I have a test line like path_directory_windows CONTAINS *\project_data\working\**\*I don’t get any errors with this syntax but it does not find the folders. Basically i am only wanting to find folders within any project_data\working folder that contain any files.If it doesn’t contain a file I am not concerned with it.Any help with a correct regex statement that would work, or the proper syntax for the contains statement are what i am needing.I have tried this regex unssuccessfullyproject_data\/working\/[^\/]+\/[^\/]+TIA

Understanding a Binary Decoder error report

Hi everyone,I’m hopeful somebody here will have seen this behaviour before and can help me to understand what’s going on. I’m getting an error when trying to decode some Base64 documents that have been read out of a system but I’m not sure why and I’m not sure I can easily create a sample workflow to demonstrate it, as I’ll explain.The task is to extract specific documents form an API connected to a document management system. I’ve been able to create a workflow that will identify the required document IDs and then extract the documents into feature attributes for me.The document data that is returned to me is in Base64 format. When I post the output data into an online conversion as a test, it is converted into a usable image (in the case that I tried). From this I assume that all other documents will work similarly.When I pipe that output into a BinaryDecoder and ask it to decode the Base64 attribute, it throws an error complaining about the input.When I copy the Base64 code and add

Choosing the Correct Transformer for removing Overlapping Line Vectors in FME

Hello. I have three line vectors in SHP format (Red, Yellow, and Green). All of them are 100% overlapping in plan, but some are shorter than the others.Which transformer should I use to remove the overlapping area from the Green line that intersects with the Yellow line, and from the Yellow line to remove the overlapping area with the Red line? Please refer to the sketch below.I tried with Clipper but it didn’t work. Thanks in advice!

FeatureWriter and Esri ArcGIS Server Feature Service with dynamic schema fails when layername contains space

I have logged a support case about my problem, but figured I might as well check to see if anyone else have encoutered this problem:I am writing a workspace to geosynchronize a Feature Service with a database. The Feature Service contains about 30 layers that need to be updated, so I have put my bet in for a dynamic workspace, since the operation is the same for every layer. This saves me a lot of transformers and makes the maintenance of the workspace much simpler.My challenge here is that both the FeatureReader and FeatureWriter requires the name of the layer to be passed in as a parameter, not the layerid, which would not be a problem. Almost all of these layers have names containing, at least, one space, and this is what is causing my trouble.On the reader side, I can enclose the layer name in double quotes, like “My Layer”, and this works without problems.On the writer side, however, things are messed up. I have so far tried three different approaches:Enter the name “as is”, like

Copy & Paste Transformer from file or web content

We generate certain types of transformers (mostly HTTPCaller) with some attributes prefilled and want our users to be able to copy the content from a file or web source and paste it directly into FME Workbench, or use drag and drop, if possible. We don’t want to use custom transformers, which works, but the overhead would be overkill. The problem is that the paste does not work, CTRL+V does nothing and the paste menu option is greyed out. I tried with a direct clone of a working transformer so the format is correct. If I copy a transformer, paste it into an editor, copy the editors content and try to paste it back to Workbench it won’t work. I don’t know why this does not work but I persume it might have something to do with encoding. Does anyone have a clue how to overcome this issue, or maybe a workaround? Thanks in advance.

Identify Changes in the GIS Schema / SchemeScanner?

The plan is to upload the workbench to FME Flow therefore my team can run it on demand.I have included a FeatureReader transformer at the beginning of the workflow to read a GDB containing cadastral polygon data. This is an User Parameter in the workbench therefore the user will be including the input.The GDB should always have the same fields/order, any variation in the scheme...the tool will fail,How can I check and inform the user at the beginning of the process that the scheme doesn’t follow the standard GIS schema?I was think about the SchemeScanner or ChangeDetector...but open to suggestionsHere is a very basic screenshot that shows two FeatureReaders → Features To Read (Only Schema),

Microsoft Word Writer and changing run order of transformers?

Hello, I have an issue with trying to use the Microsoft Word Writer. As far as I understand, I can build my Word document using multiple MSWordStyler transformers, and depending on the order of these, the document will be built differently. For example, if the “heading” goes in first, it will be at the start of the document, but if it goes in last, it will be last in the document. I have 2 MSWordStyler transformers, one table and one paragraph. I want the table to be first and the paragraph last. I got my desired result, but when I later saved my workspace my paragraph now ends up first and the table last. The order of which FME is reading the transformers has also changed. If I understand correctly FME runs the transformers in the order they appear in the Navigator, and you’re supposed to be able to change the order. I can’t do this though? I don’t get the option to move transformers up or down. I’m also supposed to be able to get the option to “Set connection runtime order” when I ri
