Hello,
I recently noticed some unexpected behavior with the Feature Merger in FME 2026.2.1.
I have a workspace where a Feature Merger combines data from three different streams. Under normal circumstances, everything works as expected. After successfully testing the workspace locally, I published it to FME Flow.
Today I noticed that the workspace failed during execution. When I opened the workspace in FME Form and ran it with Feature Caching enabled, I was surprised to see that the Feature Merger did not merge features that clearly shared the same key values:
What makes this even stranger is that if I right click the transformer and select "Run Selected Objects and Any Required Upstream Objects" a second time, the merge completes successfully without any changes to the workspace or source data.
Has anyone experienced similar behavior with the Feature Merger in FME 2026.2.1? Could this be a caching issue, an optimization problem, or possibly a defect?
Thanks in advance for any insights.
