Issues with looping (in a case of mesh smoothing)

 Hi folks, 

I'm having some issues when setting a loop. I input a TIN in loop,and then I do some processing (smoothing). At the end I've set a parameter to match; if it doesn't , then I want the TIN to be reprocessed (with a new value for refinement). 

 

I seems like the loop is not accepting a TIN as a trigger for the next loop, or this is what i understand from the log: 

  

Loop to testLoop_INPUT1620857756 Input Splitter (BranchingFactory): Transformer/Factory testLoop_Clipper_5_Solid is blocking and cannot be used in a loop, but was found between 'Loop to testLoop_INPUT1620857756 Input Splitter' and 'testLoop_INPUT1620857756 Input Splitter'

 

Transformer/Factory testLoop_Clipper_5_Solid is blocking and cannot be used in a loop, but was found between 'Loop to testLoop_INPUT1620857756 Input Splitter' and 'testLoop_INPUT1620857756 Input Splitter'

testLoop_VolumeCalculator_9_GQuery (GQueryFactory): 

A fatal error has occurred. Check the logfile above for details

testLoop_Clipper_5_Solid (SolidIntersectionFactory): 

testLoop_Clipper_5_Solid (SolidIntersectionFactory): A fatal error has occurred. Check the logfile above for details

 

Do you have any idea how to overcome this issue? 

 

Thank you very much, 

 Jorge

Read this article on Looping with Blocking Transformers (safe.com)

It's a little complicated at first 😀

hi @caracadrian​ ,

I read the article and tested the sample. I am able to run the main workspace without any issue. Not so, when running the new instance (the saved customer transformer).

 In the transformer, I am not able to set blocking parameters (in advance menu), neither the "Enable blocked looping", nor "the max. number of iterations". I am guessing this could be because the new FME version doesnt have these parameters (see image below). Do you know what could be happening here?

 

And the error I am having, when running this instance is >

Pretty much the same issue I had in my own case.

Thank you,

Jorge

I have similar issue, loop works if incoming and outgoing number of records are same.

It blocks when I do list explode incoming feature and take only of these group feature for loop, then it blocks !

I couldn't really understand the safe help, the version I'm using and help screenshots doesn't match !

Anyone else found this issue ? come across a solution ?
