Thomas Andraschko updated DELTASPIKE-729:
-----------------------------------------
Description:
If you define h:head within your site and use ds:windowId
(ClientWindowRenderMode.LAZY), then f:viewAction is called twice (2 window ids
are generated)
This was already fixed since 0.7 but broke the lazy new window detection.
i will not try to find a workaround via flash scope.

A testcase is attached.
Start application and open http://localhost:8080/jsftest22/mypage.jsf
You can see in the logs, that the viewAction is called two times.
If you remove h:head from site, viewAction is called only once, which is the
correct behaviour.
If you don't use ds:windowId and have h:head defined, then viewAction is also
called only once, which is the correct behaviour.
I don't know if this is a deltaspike bug or a bug within myfaces.
> f:viewAction is executed twice with LAZY window handling mode
