Uli,
Just to throw something out for thought which may not provide any help...
Are your tabs really so dynamic that you can't simply create a
facelets xhtml template file for each one and include them
conditionally? Or use the facelets c:forEach to generate them at
page-build time?

Sure, I should have done that from the start. I also forgot to list
some vital version numbers - which proves that I couldn't really
think anymore yesterday evening...
Anyway, I am using java 1.5 in a Linux environment, tomcat 5.0.28,
myfaces 1.1.5-SNAPSHOT, tomahawk-1.1.5-SNAPSHOT, spring 2.0RC1 and
tons of other stuff which is probably not that important.
I'm creating my HtmlPanelTabbedPane on the fly in the get-method of
my bean, like this:
public HtmlPanelTabbedPane getTabbedPane() {
if (_tabbedPane == null) {
_tabbedPane = new HtmlPanelTabbedPane();
_tab = new HtmlPanelTab();
_tab.setLabel("Blah");
_tab.setId("PanelTab");
_tabbedPane.getChildren().add(_tab);
Application app = FacesContext.getCurrentInstance().getApplication();
_tree = (HtmlTree)app.createComponent(HtmlTree.COMPONENT_TYPE);
_tree.setClientSideToggle(false);
_tree.setShowRootNode(true);
_tree.setValueBinding("value",
app.createValueBinding("#{myBean.treeModel}"));
_tree.setVar("node");
ValueBinding binding = app.createValueBinding("#{node.description}");
HtmlOutputText text = new HtmlOutputText();
text.setValueBinding("value", binding);
_tree.getFacets().put("node", text);
_tab.getChildren().add(_tree);
}
return _tabbedPane;
}
As you can see, it's a stripped down example of what I want to do
in the end, currently I'm just creating one tab, but you get the
picture. There's a corresponding set-method, too.
My template contains:
<form jsfc="h:form" id="myMainForm">
<h:panelGrid columns="2">
<t:panelTabbedPane bgcolor="#CCFFFF" serverSideTabSwitch="true"
binding="#{myBean.tabbedPane}">
</t:panelTabbedPane>
<h:panelGrid columns="1" binding="#{myBean.panelGrid}">
</h:panelGrid>
</h:panelGrid>
</form>
As you can see, I have a panel grid as second element in my outer panel
grid, which is created roughly the same way:
public HtmlPanelGrid getPanelGrid() {
if (_panelGrid == null) {
Application app = FacesContext.getCurrentInstance().getApplication();
_panelGrid = (HtmlPanelGrid)app.createComponent(HtmlPanelGrid.COMPONENT_TYPE);
_panelGrid.setColumns(1);
_panelGrid.setValueBinding("value",
app.createValueBinding("#{myBean.panelGrid}"));
....
}
return _panelGrid;
}
But I don't think it's playing a vital role, I've just listed it here
so that the template makes sense to you. I have some HtmlInput stuff
in it, that's why I need the form.
CU,
Uli
