Hi Erik,

I added this to the model declaration:
<xforms:model id="decor-datasets" xxforms:external-events="clear-locks-submit">

this action in the model:
      <xforms:action ev:event="clear-locks-submit">
            <xforms:send submission="clear-locks"/>
         </xforms:action>

and the script in the model:
         <xxforms:script ev:event="xforms-ready"
            >
            window.onunload = function() {
            ORBEON.xforms.Document.dispatchEvent('decor-datasets','clear-locks-submit');
            }
         </xxforms:script>

But it doesn't work. Am I doing something wrong?


Are there any plans to implement the xforms-model-destruct event? This would seem like a good place to put 'housekeeping' actions, it seems to me that this would also be more reliable as it does not rely on the client triggering an event.

regards,

Gerrit
