[JBoss jBPM] - Re: At end of task, return to

by woo37830

On the tasks.xhtml page I found the section where there was a view="form" and changed the <n:nav input="submit" to use a url="home.jsf" /> <n:nav input="cancel" to use a url="home.jsf" /> and removed the redirect="true" This causes the task to go back to the home.jsf when completed. Also added a button to the comment page so that if you clicked "Cancel" it went directly to the home page. The Save button on that page also goes directly to home after saving the comment.

[JBoss jBPM] - <URGENT> I need your help desperate: How to stop jbpm proces

by yalag

I'm been working for the last 28 hours, I cannot find the answer. I beg for your help. I've searched the documentation of jbpm, nothing. I've read all the java doc also nothing. One of our jbpm process has a chance of running really long (20 hours+). We would like an ability to stop it. The process is spawned off from tomcat as a seperate thread. But because java does not allow killing of threads, there is no way to stop it. Interrupt() does not help because the thread is not blocked, it simply is running busy for VERY LONG. What would be a way to stop it?

ok... great that it works... can you file a jira issue for the 'misleading' docs? so it won't get lost View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179889#4179889 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4179889

[JBoss jBPM] - Node thread safety issue

by joe_jboss＠freemansoft.com

The Node class has a potential deadlock condition in getLeavingTransitionsMap() if multiple users attempt to leave the same node at the same time. The leavingTransitionMap.put() method isn't thread safe so multiple threads can deadlock there. Other configuration methods are not thread safe but they don't matter because they are only called one time at startup.

[JBoss jBPM] - Re: Timers in jBPL

by juergen_lampe

This was THE hint - now it works as expected: <state name="warte 1"> | <timer name='reminder' | duedate='2 minutes' | transition='ex1' | cancel-event='node-left'> | <script> | System.out.println("Timer fired "+node); | </script> | </timer> | <transition to="Ende" name="ex1"></transition> | </state> | But the docu is misleading, saying: anonymous wrote : this attribute is only to be used in timers of tasks. it specifies the event on which the timer should be cancelled. by default, this is the task-end event, but it can be set to e.g. task-assign or task-start. ... Thanks a lot!

Fat change, since it was not intended to be end-user targeted with these kinds of specific wishes. the jsf4jbpm code and to some extend the gravel code is your best option to see what realy happens btw building a custom ui for a processdefinition with seam/jsf is fairly quick. Personally, I'd leave the 'back to home' out in the demo and just mention that it will be in there in the final version. I did that once and had no problem at all with this customer.

small correction: timers are only cancelled when they are on a task that is ended. So either use a cancel-timer in a transition or define the cancel-event attribute on the timer and set it e.g. to node-leave View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179837#4179837 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4179837

[JBoss jBPM] - Re: At end of task, return to

by woo37830

More, In task.xhtml we have a section in an <h:form> where <j4j:taskForm transitionTarget="#{transition}" which will cause the transition to occur and assign the task to the next actor. Then there is a <j4j:loadTask to cause the loading of the task unless the button pressed was 'cancel', Next follows the applyVariableMap, and then a mysterious <j4j:addComment. Now if I remove this, a comment is still added! It would appear as if that was the purpose of this statement, but alas! The a <j4j:completeTask. Now here is where I think something might be altered, but I don't know how. What does navigate="false" mean? what are the <n:nav outcome="cancel" redirect="true" storeMessages="true" statements doing? Is there a place where this is explained? I'd be glad to RTFM if I could locate one that had this translated in it!

btw, your first example is wrong. You cannot (and should not) cancel the timer within itself. The cancel timer should be on the transition, and it might even be left out completely, since (afaik, but you should check) a timer on a node is cancelled when this node is left.

[JBoss jBPM] - Re: At end of task, return to

by woo37830

Understand it's all basic JSF. Question is, which jsf tag and where to put it in order to have Cancel and Submit send the user back to the preset home.jsf? Yes, understand about the end-user, just no time at present as we are having to do a proof-of-concept to get the go-ahead to do the end-user UI. Would appreciate just a bit more info. Also, How do I prevent the "Comment" automatically following each task completion?
