Hi Srinath ,
tnx for the tip. It works. Thanx again.
Still I don't understand why
event.getComponent.findComponent("someID") works under ValueChangeEvent,
but under ActionEvent it returns null.

Sorry for a Wrong tip. viewRoot doesn't render anything and hence it
cannot be added as a partial target. One simple solution could be wrap
all your contents with a panelGrouplayout component and add it to the
partial target.
You can use the binding attribute to get the instance of the
panelGroupLayout or any other component in your managed bean
<tr:panelGroupLayout binding="#{DialogMB.panel}">
..
</tr:panelGroupLayout>
in your managed bean
CorePanelGroupLayout panel; and a getter and setter for the same.
-Thanks,

Hi,
tnx for the tip, but it doesn't work.
here is my code:
--- Managed bean "DialogMB"----
public void returnContactDetail(ReturnEvent event){
RequestContext.getCurrentInstance
().addPartialTarget(FacesContext.getCurrentInstance().getViewRoot());
}
--- Close button on Dialog ----
public void closeContactDetail(ActionEvent event){
RequestContext.getCurrentInstance
().returnFromDialog(null,null);
}
--- JSF code ---
<tr:commandLink text="details" action="#{DialogMB.contactDetail}"
useWindow="true" returnListener="#{DialogMB.returnContactDetail }" />
after closing the Dialog the page is not refreshed and in server log I
get this exception:

It looks like FacesContext.getCurrentInstance.getViewRoot()
returns null?!!
The same thing happend if I want to partial update anything using
actionListener. For example:
public void changePremiums(ValueChangeEvent event){
RequestContext.getCurrentInstance().addPartialTarget(event.getComponent().findComponent("someComponent"));
} <-- this code works on changeListener
public void changePremiums(ActionEvent event){
RequestContext.getCurrentInstance().addPartialTarget(event.getComponent().findComponent("someComponent"));
} <== but here I get the same exception if I
want
to refresh something pressing commanButton
Is this a bug or some feature that I don't understand?!
Best regards
Luka
