modalPanel and generation of component tree

[kphilipp]

I use the modalPanel component as follows:

<rich:modalPanel id="spSubscriberPanel" minHeight="400" minWidth="625" style="overflow: auto;">
 <f:facet name="header">Subscriber Data</f:facet>
 <f:facet name="controls" />
 <a4j:form>
 <a4j:include ajaxRendered="true" viewId="/pages/show/subscriberData.xhtml" />
 </a4j:form>
 </rich:modalPanel>

Nothing out of the ordinary until now.

The issue is, that the component tree provided by

/pages/show/subscriberData.xhtml

is already generated if the whole webpage is accessed the first time and although the modalPanel component is not displayed.

As a consequence, methods of the backing bean with unnitialized objects are invoked.

Is it possible to postpone the generation of the component tree for

/pages/show/subscriberData.xhtml

until the displaying of the modalPanel component is actually demanded by the user.

Hello,

No it's not possible currently. As a workaround you can use the fact that viewId can be defined by EL-expression. I.e. you can initially point viewId to simple basic page and then, when the modal panel is requested by user, re-render its contents using complete (subscriberData.xhtml) viewId and show panel.
