I could use some help with how to end or close blocking tasks in a task node. Here is my scenario: I an able to successfully move a token through the nodes in my workflow using the processinstance.signal method. The process has 4 nodes named START, R, S, END. Node R is a task node. A simple test of the work flow works fine. I can move the token through the work flow using the signal method as shown in the examples. After this initial test, I added a single task to the R task node. The new task is named AssignMacAddress. AssignMacAddress is blocking and signalling. I can see that the process moves through the AssignMacAddress task and calls methods for the assignment and controller classes I have associated to it. Now when I attempt to signal to move from node r to node s, I get java.lang.IllegalStateException: task-node 'R' still has blocking tasks. My question is how do I end or close the blocking AssignMacAddress task so that the process is able to move from node r to s without throwing the error? I have tried a number of approaches, none of them work. Thanks in advance. Steve View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166733#...
