Hi All,
I have a JSP which uses tiles.
The left menu part of the JSP needs to be programmatically created as
the left menu will differ based on the role the use plays.
In the leftNavigationMenu.jsp – included as a tile in layout.jsp I have
the following code:
<t:div id="subnavigation_outer" forceId="true">
<t:div id="subnavigation" forceId="true"
rendered="#{navigationMenu.leftPanelNavigationConstructed}"
binding="#{navigationMenu.parentUIComponent}">
</t:div>
</t:div>
In the method isLeftPanelNavigationConstructed HtmlPanelNavigationMenu
component and child HtmlCommandNavigationItem components are added to
the DIV component with id=”subnavigation”
At the end of creation of this menu when I view the children of
UIViewRoot then all the components are seen and are properly added.
However when the JSP gets displayed nothing is displayed in the left
navigation.
I am puzzled and I am not able to find a reason. Even though the
UIViewRoot contains the components still it is unable to render any of
the components.
Are your components nested within a "namespacing container", eg a table
or a subview? If so, the id will have a prefix eg
"subviewname:subnavigation_outer".
Also, when using JSF 1.1 with JSP, on first page render components are
created and rendered in one pass. That means that when a component is
being processed, any components further down the page don't yet exist
(and so cannot be found). Using JSF1.2 (not yet implemented by MyFaces)
or Facelets solves this.
