Workflow Task, Require the Comment to be filled out?

[sdrzewiczewski]

Can a Transition be used to ensure that the comment on a default task page is not left blank?

My use case is if somebody Rejects something, I want them to provide a justification, but if they approve it they do not need to provide a justification.

If it can be done, how do you address the comment field on the task page?

Thanks,
Steve D.

I've done this in 8.0 by creating my own TaskCompleteDelegate class
which processes the results of a Task Complete operation. If no value,
simple throw a WTException with a message. You can also do this with
transitions I believe.

Need to use a workflow variable for the comment (rather than a comment box), then make the variable required.

I think he was looking for a conditional required variable.
