Cant wire pop up

[hahnz]

HI XIaochong, I have a problem again with wire popup...

here's my code in gsp:

            <z:popup id="pop1" width="300px">
<z:menubar>
    <z:menuitem tooltip="save" label="${message(code:'default.button.create.label',default:'Enregister')}" id="saveButton"  image="${resource(dir:'images/skin',file:'database_save.png')}" />
    <z:menuitem tooltip="cancel" label="${message(code:'default.button.cancel.label',default:'Anuller')}"  id="cancelButton" />
    <z:menuitem label="Dupliquer" />
</z:menubar>
            </z:popup>

and here's the composer: class ListComposer { Window self Popup pop1

void onClick_cancelButton(Event e) {
    pop1.close()
}

and here's the error in grails

The class 'nc.mairie.pdc.usageconstruction.ListComposer' has a null instance state manager object, instance is nc.mairie.pdc.usageconstruction.ListComposer@d6245a

what did I missed?

its not error

but if I type this: Window self Popup pop1 Textbox nom Grid grid ListModelList listModel = new ListModelList() Paging paging

I got error?

If encountered an error 'has a null instance state manager object',you can try 'grails run-app' command to restart app.
