HtmlTabPanel class cast exception
Hi everybody,
In my xhtml page I have the following line
<rich:tabPanel id="myId" binding="#{form.tabPanel}" />
and in the form backing bean I put the following code
private HtmlTabPanel panel;
public void setTabPanel(UIComponent panel) {
if(this.panel == null) {
this.panel = (HtmlTabPanel) panel;
HtmlTab tab = new HtmlTab();
tab.setTitle("Tab 1");
tab.setDisabled(false);
HtmlTab tab1 = new HtmlTab();
tab1.setTitle("Tab 2");
tab1.setDisabled(false);
tab.setParent(this.panel);
this.panel.getChildren().add(tab);
tab1.setParent(this.panel);
this.panel.getChildren().add(tab1);
}
}
public UIComponent getTabPanel() {
return panel;
}
I added three modules
<module> <ejb>richfaces-ui.jar</ejb> </module> <module> <ejb>richfaces-impl.jar</ejb> </module> <module> <ejb>richfaces-api.jar</ejb> </module>
in my application.xml, I put the corresponding jars in the base directory of my ear file and I removed richfaces-ui.jar and richfaces-impl.jar from the WEB-INF/lib dir of my war.
When I load the page I get
GRAVE: Error Rendering View[/dojo_comp_ext.xhtml]

I also looked in the manifest of those jars and found out they have
Specification-Version: 3.1.2.GA and Implementation-Version: 3.1.2.GA.
I generated the project with Seam-gen 2.0.0GA. I also searched jboss-4.2.1.GA for conflicting richfaces jars, but I did not found any.
Any idea about what is going on?
Thanks in advance,
ciao Francesco
