Re: {Spam?} Dynamically Assigning Users to Participants

Greg,

Maybe you can place a break point in the class throwing the exception and 
see which expression is the one Shark is complaining about..?

Subject
{Spam?} [shark] Dynamically Assigning Users  to Participants






I'm trying to use the ArbitraryExpressionPerformer.
 
Here is what I've done so far:
 
1. Created a process and defined two activities.  Both of these activities 
are in the "default" ArbitraryExpression "swimlane"
2. Created two process variables under JAWE's Workflow RelevantData tab 
called "pone" and "ptwo" - both are Basic Type - String
3. Under JAWE's activities tab, I assigned pone to be the performer of 
activityone and ptwo to be the performer of activitytwo
4. The script type for the package properties is set to text/javascript
5. I changed the Shark.conf file as follows, commenting out the default 
and adding the new one:
#AssignmentManagerClassName=org.enhydra.shark.assignment.StandardAssignmentManager 

 
AssignmentManagerClassName=org.enhydra.shark.assignment.XPDLStraightParticipantMappingAssignmentManager
6. I create the process and assign the process variable pone to "UserOne" 
and ptwo to "UserTwo".
7. I start the process
 
If I look in the database, a resource of "UserOne" has indeed been created 
for the first activity.  But that resource doesn't seem to be connected to 
the user called "UserOne".  If I look at UserOne in the admin tool, using 
they have no tasks.
 
My server is throwing a "Expression can not be evaluated" error - is there 
something I missed in trying to use the ArbitraryExpressionPerformer??? 
I've looked through the archives and managed to figure out these steps, 
but found no information that would indicate what the problem is.
 
Thanks for your time,
Greg
