define task description in flux

Hi... I’ve got a problem when I’m trying to define the description of a task (task description).

Here is the code :

<task-node name="Request claim by driver">
    <description> Inform the chronology of accident to admin staff </description>
    <task swimlane="Worker">
        <description>Filled in Chronology Form</description>
    </task>
    <transition to="Prepare Required Documents"/>
    <event type="node-enter">
        <action class="com.twproject.task.process.TaskProcessTaskNodeEnterHandler"/>
    </event>
    <event type="node-leave">
        <action class="com.twproject.task.process.TaskProcessTaskNodeLeaveHandler"/>
    </event>
</task-node>

And after I Ioad the flux,,"task description field" for that task is still blank....
I have no idea how to solve this...
Any help will be greatly appreciated....
Thanks for your time...
