Hi Simon,
Yes the outer DIV component with id="subnavigation_outer" is enclosed in
a subview naming container in the layout.jsp. Following is the code
snipped:
<td width="170px" valign="top" bgcolor="#F8F6F7" nowrap="nowrap">
<f:subview id="leftnav">
<tiles:insert attribute="leftnavigation" flush="false"/>
</f:subview>
</td>
Do you mean to say that in my JSP for left navigation I need to prefix
the naming container id if any? Why is this necessary?
As you can see from the code below I get the inner DIV component via
value binding. It gets me the correct component.
I am able to populate and add a HtmlPanelNavigationMenu to the DIV
component. If then I look at the entire tree then the components added
are present.
If the components are added properly then when it goes to the render
response phase then it should get all the components.
I am missing something or have I misunderstood something.
