 I have some strange behaviour that Im hoping Safe can confirm, I have built a very simple loop in 2026.2 using the new looping functionality, it runs fine every time.  I then encapsulate that into a custom transformer, thats where the weirdness starts.  Running with caching OFF everything behaves itself...

I then turn caching ON and the loop on the canvas behaves as expected, but the custom transformer containing the SAME loop doesn’t…

Inside the custom transformer…

The Loop doesnt initiate, when caching is ON, I cant work out why?

I have attached the workspace.

    Hi ​@drewhutchinson I’ve filed FMEFORM-38616 after confirming that the loop in the embedded custom transformer doesn’t work when data caching is on.  Thanks for reporting this. There’s no issue if the custom transformer is linked.
