Define schema in XML file and render it as flowchart blocks on web page -> What exactly do you want to render?
It means you define the clinical guideline for a patient as a XML schema. Then jBPM engine should dynamically create the flowchart on webpage as per teh schema. It should display the flowchart.
After rendering user should be able to add and delete flowchart controls -> What do you mean by flowcharts controls?
Flowchart controls means each node of flowchart i,e the rectangluar box , decision box etc.
The funcitonality like, user should be able to delete any box on the fly and schema shld be updated. If user want to modify guideline, the same can be added/deleted on the fly.
