I would assume (dangerous in this case), that a Terminator would halt processing completely.

I have a workspace, that imports from a WFS. It errs because the provider made a breaking change by removing a column in the read dataset. This issues a rejected feature, which triggers a Terminator.

But even then, the postprocess action of my SQL writer is triggered.

Why does this happen ?

If a terminator is called, it indicates that the workspace has failed. And then triggering postprocessing is a dangerous action, as this usually requires the writing to have been completed without errors.

Is this not a bug ?

Using FME 2022.2.6 on FME Server/Flow.
