Hello,
1. Is the entire tree created before rendered property is checked?
- Yes... and no... It will be fully built most of the time on
postback and almost never on new rendering... which kind of
****, but it's
how its work as you can find out when checking the Tag code.
2. Is a component added to the UIViewRoot only if rendered ="true"?
- No, it's always added (95% sure).
Regards,
~ Simon

Hi All,
Sorry about the last mail – there was no greeting and no subject.
Here is the mail content again:
I am using tiles along with Myfaces.
My layout.jsp contains the following parts
<definition name="layout.tiles" path="/common/layout.jsp">
<put name="header" value="/common/header.jsp" />
<put name="topnavigation" value="/common/topnavigation.jsp" />
<put name="leftnavigation" value="/common/leftnavigation.jsp"
/>
<put name="body" value="/common/blank.jsp" />
<put name="footer" value="/common/footer.jsp" />
</definition>
I need to generate leftNavigation menu programmatically. So in my
leftNavigation.jsp I have included the following code:
<t:div id="subnavigation_outer" forceId="true">
<t:div id="subnavigation" forceId="true" rendered="#{
navigationMenu.leftPanelNavigationConstructed}">
</t:div>
</t:div>
navigationMenu.leftPanelNavigationConstructed – This method has the
following code to identify the parent UIComponent which is <t:div> component
with the ID= "subnavigation"
*Following is the code:*
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
UIComponent parentUIComponent = context.getViewRoot
().findComponent("subnavigation");
The problem is that parentUIComponent is coming as *null*
The method mentioned in the rendered property gets called but it is not
able to recognize the component for which it was called. I have following
questions:
1. Is the entire tree created before rendered property is checked?
2. Is a component added to the UIViewRoot only if rendered ="true"?
Any help will be appreciated.
Rgds,
Madhav
