Passing values between task nodes

[harpritt]

Hi lads and ladies


Below is part of my process.

what i would like to know is if there is a way to pass a conversation scoped variable that is available to the desision node on to the task-nodes.

#{changerequest} is outjected to the desision node but is not available to the task-nodes because it is outside the scope.

any ideas are greatly appreciated .....

<decision name="decide" expression="#{#somthing.expression}">

 <transition name="yes" to="approver_approve_CR"/>
 <transition name="no" to="assign_approver_to_CR"/>
 </decision>

 <task-node name="assign_approver_to_CR">
 <task name="assign_app_to_CR" description="unknown">
 <!-- This will appear in the pooledtasklist not the taksList -->
 <assignment pooled-actors="CRS_Processor"/>
 </task>
 <transition name="submit" to="approver_approve_CR"/>
 </task-node>

 <task-node name="approver_approve_CR">
 <task name="ap_approve_cr" description="#{crId}">
 <assignment actor-id="#{changerequest.crApprover}"/>
 </task>
 <transition name="accept" to="process_CR"/>
 <transition name="reject" to="editor_revise_CR"/>
 </task-node>

Have you tried adding a controller to your task node? eg:

 <task-node name="MyTaskNode">
 <task name="myTaskName" description="#{taskDescription}">
 <controller>
 <variable name="myVariableName" access="read" />
 </controller>
 <assignment pooled-actors="#{taskAssignToPool}"/>
 </task>
 <transition name="resolved" to="done"></transition>
 </task-node>

Cheers,

Hi Pete

I didnt want to add it to the bussines process scope as its not used after the first task, i thought it would be a bit of a waste.
