[jboss-user] [JBoss jBPM] - 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
