Now I am developing free ERP (http://www.coolerp.com) software by Adobe Flex. I have evaluated many workflow engine. Most of them are not suitable for us. After tested activiti workflow, it's amazing. This is what we need. But it seems the main interface is written by JavaScript with yahoo interface. Now I have to re-written the UI or communication interface by activiti's protocal with Flex/Actionscript. Our demo site is http://demo.coolerp.com. So I want more support from you team. Later we will contribute the interface to this site. Need your team's suggestion.
What we need is about interface specification of workflow engine.
As I understand, the interface are some xml file. Is there any document describe it from development point of view. As you know we need to redesign workflow designer with Adobe Flex.
