+10I recently tried to update an older workspace with a TestFilter that is used to branch data out using basic logic. After the update, the workspace failed in an odd fashion and after a bit of troubleshooting it turned out that one of the tested attributes, “fme_feature_type” in this case, was getting changed to nulls for many, but not all of the resulting rows. The change was from TestFilter Version 2 to Version 3. Has anyone else experienced anything similar? I’m running FME Form Build 25815.
+10Found another tidbit on this. The TestFilter is immediately downstream from a CommonLocalReprojector transformer. If I update the TestFilter but not the CommonLocalReprojector the bug seems to disappear. Maybe this is a problem with the Version 3 CommonLocalReprojector?
+20Sounds like the issue is with the CommonLocalReprojector. Deleting and re-adding it may work, if it was created in a workspace before ~2023, run now in 2025, even if it’s the same transformer version. If its behaviour of dropping the fme_feature_type changes if you have less than 1000 features, then report it to Safe as a bug.
+15Hi @pmcpherson,
I wasn’t able to reproduce this issue when upgrading a sample workspace from 2022.2 (version 2 of TestFilter & CommonLocalReprojector) to 2025 (Build 25815). If the ctredinnick’s suggestions didn’t resolve it, could you please share a minimum workspace along with sample datasets so we can reproduce the issue and dig in further?
Also if you’re only filtering fme_feature_type with the TestFilter, I’m curious if you observe the same thing if you swapped it with the dedicated FeatureTypeFilter transformer as well.
