Jdev11g: Possibility to determine component which has the focus ?

Question

Hi,
we have a customer request to display (internal) informations about the field and the corresponding VO which has the cursor focus at the moment (for problem analysis purpose)
If the mouse cursor is in an input field and the user press a button or select a context menu he want to see this information e.g. in a popup.
Is it possible to determine the component ID of the field which has the focus? (hopefully the input field does not loos the focus if user opens e.g. the context menue)
If yes, whats the best way to find from the component ID to the corresponding VO?

Peter, sorry for the mix up.
getContextComponent(..) is one of my private helper methods for a special case. I think you don't need it in your case. Check the UIComponent you get back from actionEvent.getSource() if it's the input field you are looking for, if not check its parent.
In my method I walk down the component tree to get a special component I'm interested in.
Heres the code:    private UIComponent getContextComponent(UIComponent aUI)
        try
            UIComponent ui3 = aUI.getParent().getParent();
            Map<String, Object> attr = ui3.getAttributes();
            String obj2 = (String) attr.get("_launchId");
            UIComponent uiXXXX = JSFUtils.findComponentInRoot((String) obj2);
            if (uiXXXX.getChildCount() > 0)
                UIComponent uiC = uiXXXX.getChildren().get(0);
                return uiC;
            else
                return uiXXXX;
        catch (Exception e)
        return null;
    }Timo
