Hi again, Looking back through the archives for the group I found this message from one of our developers... "Workbench has some special code that allows the AttributePrefixer (and others) to do their magic and add these attributes dynamically."
Since the AttributePrefixer was what I based this on, I think these attributes may not get automatically exposed without some Workbench tinkering. Damn. I really thought it was OK. I'd already filed an enhancement request to get such a transformer added to FME, so we'll see what happens with that one. In the meantime, the attributes are properly renamed (you saw them in the Viewer), so you could write them to a destination dataset, even if you can't see them; or use an AttributeExposer to manually expose them. A pain I know, but it's all I can think of. I guess you could try and copy the TCL code from the transformer into a TCLCaller; but I don't think that will make a difference, since that won't expose new attributes either. Sorry about that - I'll let the group know if and when the enhancement request is implemented.
