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
