Sending message back to user from failed workflow transition

[avillanueva]

Workflow transitions are a nice place to drop in code and run checks off a user task. I have a few versions of the "check in your changeable stupid" validations before the workflow changes their state. In one version, it's a simple if/then expression that sets result to true or false:
if (user.hasBrain())
result=true;
else result=false;
The user would get an message like this if false: COMPLETE transition expression for Check In Resulting Items returned false. Kind of cryptic for yee of few neurons. I could explain this with a little training but does anyone else relay clear messages back to the user? I believe I can throw a WTException with a message which will get displayed, I think. Just curious if that causes the task state to have issues.

I have used following in transition without issues.

java.lang.Exception e = new Exception("Please make sure the XYZ is checked in before completing task");

if(wt.vc.wip.WorkInProgressHelper.isCheckedOut((wt.vc.wip.Workable)primaryBusinessObject)){

result=false;

throw new wt.workflow.engine.FailedTransitionException(e);

}

I built off that to produce a similar I-D-10-T error message.
