I have some views which need to be able to work both as dialogs and
as 'regular' views. I need to be able to close the dialog if the view
was opened that way, so I added a call to
RequestContext.returnFromDialog(). But when not in a dialog, this
causes an exception as shown below.
The obvious thing to do is to check if a dialog is active before
calling returnFromDialog(). I tried to do that with a guard around
the returnFromDialog() call:
rc = RequestContext.getCurrentInstance();
if (rc.getDialogService().peekView() != null)
rc.returnFromDialog(...);
but peekView() always returns null, even when in a dialog. So how do
I determine if it is necessary to call returnFromDialog()? Do I have
to track whether the view is a dialog myself, or is there some
'standard' means of querying for it?
