Michael Heinen commented on MYFACES-1430:
-----------------------------------------
Here is another szenario where selectMenu looses values with myFaces core 1.1.4
!!!
On page1 is a selectMenu with componentBinding.
The corresponding BackingBean has sessionScope.
On this page1 I click an outputLink to page2.
On page2 I click another outputLink back to page1.
Then the selectMenu on page1 is empty !!!!
This is also not the case with myFacesCore 1.1.3
The used version of tomahawk is again 1.1.3.
This bug makes the whole myFaces core 1.1.4 unuseable!
I need really urgent a patch for this critical bug.
Here are the code snippets to reproduce it:
Page1:
<html>
<head>
</head>
<body>
<f:view>
<h:form id="myform">
<h:outputText value="Menu"/>
<h:selectOneMenu id="savedSearchesMenu"
binding="#{BBController.savedSearchesMenu}"/>
<h:outputText value="<br/><br/>uiItems" escape="false"/>
<h:selectOneMenu id="uiItems" value="empty">
<f:selectItems value="#{BBController.selectItems}"/>
</h:selectOneMenu>
<h:outputText value="<br/><br/>" escape="false"/>
<h:outputLink value="/ddTest/faces/page2.jsp"><h:outputText
value="doOutpoutLinkToPage2"/></h:outputLink>
</h:form>
</f:view>
</body>
</html>
page2:
<body>
<f:view>
<h:form id="myform">
<h:outputLink value="/ddTest/faces/page1.jsp"><h:outputText
value="doOutpoutLinkToPage1"/></h:outputLink>
</h:form>
</f:view>

> After updating myFacesCore to 1.1.4 a selectOneMenu with a binding is not
> working anymore.
> The used version of tomahawk is 1.1.3.
> The entries of the select one menu are cleared after clicking an immediate

> The BackingBean BBController has session scope.
> When I go back to myFacesCore 1.1.3 everything works fine!!!
> I attached a small demo webApp that everybody can reconstruct this behaviour.
