[jboss-dev-forums] [Design of JBoss jBPM] - Extension of the Designer

[magro1202]

Hi everyone, Hi Koen

i'm doing a diploma thesis at a company in Germany which is working with the JBPM Workflow Engine.

they want me to extend the Workflow Designer to have a possibility to specify an action node for their special issues.

At the moment they add specific Elements manually via XML-Editor, but 
with complex Workflow structures this is not efficient and very error-prone.

the Elements they want to specify looks like this for example


  
    
	 
	 
	
        
      	  
      	    
      	    
      	    
    	
    


There can be further elements within the "call" - Tag for example invoke or result parameters of an ant-script that is specified by scriptName

processVariables are global Variables within the Workflow that must be defined in an action node.

so my work is to implement a generic interface to be able do those configurations via the Designer

the idea is that with such an interface every user can load a specific definition in the designer to offer user dependant configuration of an action node.
For this i considered to create a new config-type for the action node e.g. "external" or "user defined" or the like.
when selected a user defined xml could be load in which the configuration elements are specified to be available in the designer

if such work is desired of a wide range of users one could transfer the results back to the Open Source Projekt

So my question is, does anyone have suggestions where in the code i have to make modifikations or extensions? 
Or does anybody recommend a better way to do that?

Any comments are wellcome and would help me a lot

Regards 
Matthias
