Hi,
I've just spend hours to track down an error in a custom Workbench transformer calling a Python transformer.
Both transformers were fine, but I finally tracked the error down to being the name I'd given the Workbench transformer which contained a dash (as in "...T-SQL..."). FME used that name indiscriminately to auto-generate the code to call the Python transformer, yielding a not very clear error message, caused by dashes not being allowed in variable names in Python.
FME do already replace blanks with underscores when naming its own transformers, so why not extend this to do the same with dashes (and all other illegal Python variable name characters) ?
