Writing custom tasks

[kannan_jboss]

Hi All,
I would like to extend JBPMs "Task" while extending other nodes is fairly easy, extending Task is not straightforward. In particular, the code JpdlXmlReader has lines like,

public Task readTask(Element taskElement, TaskMgmtDefinition taskMgmtDefinition, TaskNode taskNode) {
 Task task = new Task();
 task.setProcessDefinition(processDefinition);
 ...........(around 80-100 lines here)

Can someone point me to some relevant Wiki articles, where we can extend the actual "Task" type. Basically I want to add some functionality to the "Task" like ability to determine the actual form to be shown to the UI when the task is manual

your last item will be addressed in jBPM 3.2. Also, you do not need to extrend the task node, but rather implement your own taskcontroller. If you want to put additional info in the task node, you can always read the processdefinition.xml from the engine, read that addditional info and use it to display things

Thanks Ron!!
Can you let know the feature request or How it is planning to be? I quickly tried http://jira.jboss.com/jira/secure/IssueNavigator.jspa?pager/start=20 and couldnt locate one?

if the Jira there is a jbpm project and a webinterface component. Some of the issues mentioned there are related to this issue. The target is 3.2 for which there is a roadmap in the jira and information on the wiki. An explicit issue for creating a 'custom' form per task is indeed not in the jira. I'll create one so it also shows up in the releasenotes.
