FIXED!!! I changed some things I attached the handler on node leave in the handler I created the new task and created a new variable using tCompDoc.setVariableLocally(varname, varvalue); then in the action to execute a task I called ti.getVariablesLocally() to obtains the list of variables defined in the executing task now I doesn't care about ti.getTask that is null i doesn't care about a taskcontroller i doesn't care about any other boring stuff thanks to syngolis! If someone has any questions about my code can ask me! regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067390#...
