Thomas Andraschko created DELTASPIKE-729:
--------------------------------------------
Summary: f:viewAction is executed twice with LAZY window handling
mode
Key: DELTASPIKE-729
URL: https://issues.apache.org/jira/browse/DELTASPIKE-729
Project: DeltaSpike
Issue Type: Bug
Components: JSF-Module
Affects Versions: 0.6
Environment: tomcat 7.0.50
java 7
myfaces-2.2.2, deltaspike-0.6 (and deltaspike-0.7-SNAPSHOT )
Reporter: Thomas Andraschko
Assignee: Thomas Andraschko
Priority: Minor
Fix For: 0.7
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)
{code mypage.xhtml}

<ui:remove>without h:head everything works correct</ui:remove>
<h:head></h:head>
<f:metadata>
<f:viewParam id="myid" name="myid"
value="#{viewParamBean.myId}"/>
<f:viewAction action="#{initCtr.initApplication()}"/>
</f:metadata>
<h:body>
<ds:windowId/>
<h:form>
#{viewParamBean.myId}
</h:form>
</h:body>
</html>
{code}
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.
