I looked at the definition of the ListBreaker and found there is a defect that the loop would repeat infinitely if the specified list didn't exist. In your data, the 196th feature doesn't have the "mere{}" list.

@Mark2AtSafe, could you please check the implementation of the custom transformer?

Thanks for checking that out Takashi. Yes, I didn't have a test in there for an empty or missing list. I've added something in there that will output the features as rejected in that case. The new version is on the hub and it should work OK for you now, @pascalmortz

Hi @Mark2AtSafe, thanks for updating the transformer.

I sometimes use the BulkAttributeRenamer (Regular Expression Replace) to convert list elements to regular attributes whose names are suffixed by the original index. The method definitely works in FME 2018 and earlier, but I noticed that it doesn't work with FME 2019 beta (build 19215).

This screenshot illustrates the issue that appeared on FME 2019 beta. Is it an intentional change or an unexpected regression to be fixed?

Thanx for all

I test now.

Ok It works properly, thanx a lot
