[jboss-user] [JBoss jBPM] - Errors during BP execution, selectionFailure

[pkovgan]

Hi!

I've got this error durin BP execution, what does it mean?

I know that failure occures during second assign, but do not know where exactly, what you can propose to debug?

This failure is very quiet , except this message I have nothing to track problem.

Thanks!
