[anleonard]

Hi, 
I use jBpm for implemets my workflow applications and JBoss as Application Server. Now i would like to assign for each my task nodes in the graph, one task that use variables from a JavaBean. I have configure tasks with Custom Controller and I have explain the JavaBean class path and the variables I want to use. After Deploy the process, I go to http://localhost:8080/jbpm, I login with "cookie monster" user but if I choose the process this is the result:
