So of course the docs should mention that there are error variables?
They do, it is just buried and not obvious.
Right after a do-start-workflow event, if there is an error, the error variable, "error.do-start-workflow" will have a value. The DirXML Example Code below will catch when there is a value for Error.do-start-workflow:
<do-if> <arg-conditions> <and> <if-local-variable mode="regex" name="error.do-start-workflow" op="equal">.+</if-local-variable> </and> </arg-conditions> <arg-actions> <do-trace-message level="3"> <arg-string> <token-text xml:space="preserve">Workflow Error Detected PLACEHOLDER</token-text> </arg-string> </do-trace-message> </arg-actions> <arg-actions/> </do-if>
Alas, Find Matching stores it as funny values of the dest-dn, strange Unicode values.
