Multiple embedded transformer woes

Hi,

I've made an embedded transformer to reproject an alphanumeric coordinate set, controlled by a published parameter set. It reads the "old" coordinates from two given attributes, and returns the reprojected coordinates values into the same attributes.

This works well enough, except when I have a dataset with two pairs of coordinates. It reprojects the first set fine, but completely ignores the latter, leaving them only partially processed.

I've tried to insert a FeatureHolder between them, but it looks like the two transformers in the same workflow interferes with each other ?

I've swapped the two transformers, and right enough, now the other set gets reprojected, while the former doesn't. So it's at least consistent.

Has anyone encountered something similar before ?

Cheers

Closing the question, as I honestly cannot remember whether it was solved another way, or just abandoned.

Are the attributes holding the coordinate values hardcoded in the custom transformer or are you handling those with parameters?

And what about the output attributes? If those are hardcoded instance 2 of the transformer will overwrite the results of instance 1.
