Is there a way to pass features in the GeometryValidator in loop until they are clean? I use to put 2 or 3 GeometryValidator in queue to do the job, but sometimes it is not enough and it is not really neat in the workspace.
Thanks a lot

Question
How to pass features to GeometryValidator in loop
I have notice that some features have to go through the GeometryValidator more than one time to be completely repaired from topological errors. I thin this happen when a feature have more than one error, but I am not sure if it is the only reason.
Hi,
yes, this is possible using a looping custom transformer.
However, be very careful as you might encounter geometries that won't repair properly, leading to an infinite loop if you don't provide for some exit mechanism after a number of loops.

Hi,
one solution could be to use a Counter with the Name set to the primary key attribute (I used the OBJECTID in the example below), so that you get a loop count for each attribute:
You can then test this loop counter before you decide to loop it once again. (A nice addition could be to use a published parameter for the loop count limit)

Very elegantly done! I actually didn't realize that several passes via the validator will have any effect! Good to know! Now just wrap it up in a costumer transformer to share with the rest.:)
