how to set the task priority on the bpmn20.xml

luisalves00

This is a simple thing but I can't find it anywhere.

programmatically:

org.activiti.engine.task
-> setPriority()

Nothing is available at the moment to specify the priority on the task-definition. Can you create a jira task for this feature?

luisalves00

here: http://jira.codehaus.org/browse/ACT-797

so how it's done at this point?

frederikherema1

Best solution I can think of is using a TaskListener and field-injection to set the priority in your definition, eg:
(don't mind the syntax, just from the top of my head)

<br><userTask id="task1" name="My task" ><br>&nbsp; <extensionElements><br>&nbsp;&nbsp;&nbsp; <activiti:taskListener event="create" class="org.activiti.SetPriorityTaskListener"><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <activiti:field name="priority" stringValue="1234" /><br>&nbsp;&nbsp;&nbsp; </activiti:taskListener><br>&nbsp; </extensionElements><br></userTask><br>

<br>public class SetPriorityTaskListener implements TaskListener {<br>&nbsp; <br>&nbsp; public Expression priority;<br><br>&nbsp; public void notify(DelegateTask delegateTask) {<br>&nbsp;&nbsp;&nbsp; delegateTask.setPriority((String)Integer.valueOf(priority.getValue(delegateTask)));<br>&nbsp; }<br><br>&nbsp; // get and set priority<br>}<br>

a little bit of hard work for a simple thing…but thanks frederikheremans, I'll do it this way

frederikherema1

That's the only workaround I could think of. You're always free to submit a patch for the issue you reported…

frederikherema1

Does it work with a single task? AFAIK, tasklisteners are called on each instance…

luisalves00

it works for all cases so far…tks

There is a slightly easier way to achieve the same thing until this is fixed. Add the following listener to the task elements:

<br><extensionElements><br>&nbsp;&nbsp;&nbsp; <activiti:taskListener event="create" expression="#{task.setPriority(100)}"></activiti:taskListener><br></extensionElements><br>

tks WalterJS…didn't try it yet…but its a lot lot easier solution
