Hidden transition

calle — Sun, 25 Jan 2009 21:57:50 GMT

HiIs it possible to create a <transition> in the process definition that does not show up in the corresponding task dialog? I would like to use such a transition for a timer that auto-completes the state. //Carl

Hi,

Can you explain me how can I do it?

In my workflow an action is execute when event "task-end" is happened. This action checks if the user has uploaded a document. If not, the transition comes back to the node, else the transition is choosen by the user. I need that the transition that comes back to the node is hidden to the user.

Thanks a lot in advance,

I found one way to do it and that was to implement a new Dialog for the manage-task action for the specific workflow task. Override the getAdditionalButtons() method in your extension of the ManageTaskDialog class.

This is a quite complex way to do it but it works.

About 2 years too late but for all other guys:

you can set the bpm:hiddenTransitions variable.

Example:
4 Transitions: OK, reject, timeout, canceled
only OK and rejected should be displayed to users.

(right now i only figured out to set the variable via java-code)

execute the action in the task-assign-event because it has to be done after task-create

in the action, just do
ec.setVariable("bpm_hiddenTransitions", "timeout,canceled");

and you are done.

More detailed:
<event type="task-assign">
<action class="com.itnovum.workflow.common.SetHiddenTransitions" >
    <hiddenTransitions>canceled,timeout</hiddenTransitions>
</action>
</event>

the java-class:
public class SetHiddenTransitions extends JBPMSpringActionHandler {
private org.dom4j.Element hiddenTransitions;
public void execute(ExecutionContext ec) throws Exception {
    if (hiddenTransitions == null) {
      throw new WorkflowException("hiddenTransitions has not been provided");
    }

    ec.setVariable("bpm_hiddenTransitions", hiddenTransitions.getTextTrim());
}

public void setHiddenTransitions(Element hiddenTransitions) {
    this.hiddenTransitions = hiddenTransitions;
}
}
