Subject Re: tobago partial rendering question
Date Wed, 14 Apr 2010 21:11:50 GMT
Hi  Michael,

not a common way, but there is always something you can do :-)

But how exact depends on the concrete situation.

You can put a tc:command  with action 1 as facet eg. inside the box2
and use the onclick attribute of the button:

On the button in box 1 remove the actionListner and add
onClick="Tobago.reloadComponent('page:form2:box2', 'page:form2:action1');"

in box2 add a tc:command as facet:

<f:facet name="action1Facet">
  <tc:command id="action1" actionListener="#{controller.action1}">
    <tc:attribute name="renderedPartially" value="box2"/>
 </tc:command>
</f:facet>

but now is the box1 not processed, so you cant get the value of string1.

If you need this then you can put the action facet on the surrounding panel.


Regards,
    Volker
