Whenever we tried to edit a workflow (it happened with EVERY workflow, but did not seem to be happening outside of workflow) we would get this error:

“Error executing code: FormRun (data source) has no valid runable code in method ‘new’.”

The first thing in this case is ALWAYS to do a compile, cross your fingers, full CIL, restart the compile because the users clobbered it, dance around the moon, incremental CIL, … no, sorry, got carried away.

90% of the time this type of error is because something did not compile. However that was not the case with me. I opened up a support case and insisted to Microsoft that the code was unmodified. However, once they got me to delve into the call stack (thanks to Scott Wright at Microsoft), I see that there WAS a modification – the security development tool!

I removed that tool, went through the checklist, and the users are editing their workflows again. *shakes head*

Next time it would be nice to post a happy post rather than “here are my problems and how I fixed them.” How about AXTech2014?

Happy DAXing!
