tabpanel selection without backing bean

[mars1412]

is it possible to pre-select a specific tab without the need of a backing bean?

I want to use switchtype serverside and I also need to select a specific tab when the page is rendered.

I'd like to use an optional URL parameter for that: so if the URL parameter 'selectedTab' exists and is not empty, I want to use it for the selectedTab attribute, otherwise the selected Tab attribute should be ignored at all.
How would I do that?
Is this possible at all?

I didn't figure out how to do that without a backing bean.

so my workaround is this helper bean:

@Name("richTabPanelHelper")
@Scope(ScopeType.PAGE)
public class RichTabPanelHelper implements Serializable {

 /** The Constant serialVersionUID. */
 private static final long serialVersionUID = 1L;

 private String selectedTab;

 public String getSelectedTab() {
 return selectedTab;
 }

 public void setSelectedTab(String selectedTab) {
 this.selectedTab = selectedTab;
 }
}

and in pages.xml I set the initial value:

<param name="selectedTab" value="#{richTabPanelHelper.selectedTab}" />

where selectedTab is the URL parameter
