Jbpm Process Designer Expression support

[fisca79]

Hi,

I'm using the current version of the jbpm process designer in order to model my workflow process. Unfortunately I need to create a variable and assign it a value at design time. Reading the jbpm documentation I found that this operation can be done using the expressions.

Example:

<task-node name="node1">




taskInstance.setVariable("var1", "value");
taskInstance.setVariable("var2", "value");





</task-node>

Unfortunately I have to insert this sintax directly into the process xml description.
My question are:
- there are some plans to add the expression support into the plugin ? (for example making an 'insert expression' directly from the gui )
- there is another way to create a variable and assign it a value at design time ?
- If not why jbpm doesn't allow to define a variable and assign a value into the process definition ? (other workflow engines do that)

Cheers
Luca

Sorry I have forgotten to insert the code tag so the xml doesn't appear:
Hope this time it will be shown:

<task-node name="node1"><task name="node_task1" swimlane="/swim">
 <event type="task-create">
 <script>
 <expression>
 taskInstance.setVariable("var1", "value");
 taskInstance.setVariable("var2", "value");
 </expression>
 </script>
 </event>
 </task>
 <transition name="" to="join1"></transition>
 </task-node>

Cheers
Luca

1: Not on the short roadmap. If it is not in the Jira, create an issue and it will (eventually) be assigned a version.

2: A generic java based actionhandler which takes it's input as normal actionhandlers do and sets the variables

3: As you can see, jbpm has 2 ways to set a value designtime. Maybe not the way you like it, but the functionality is there
