--------------------------------------------

Is this issue already fixed [~werpu]? So we can "resolve" it instead of letting it open.

> After releasing MyFaces 2.3.1, I noticed a regression in cross form submit from Spec Issue 790: [https://github.com/javaee/javaserverfaces-spec/issues/790]
> HTML sample code:
> {code:java}
> <h:form id="a"> 
> <h:outputText value="This is 'form a' " /> 
> <h:outputLabel for="input1" value="Enter a new value for input1: " /> <h:inputText id="input1" value="#{simpleBean.input}" /> 
> <h:commandButton id="submitButton1" value="Click here to execute 'form a' and 'form b' but re-render 'form b'"> 
> <f:ajax execute="a :b" render=":b" /> 
> </h:commandButton> 
> </h:form> 
> <h:form id="b"> 
> <h:outputText value="This is 'form b' " /> 
> <h:outputLabel for="input2" value="Enter a new value for input2: " /> <h:inputText id="input2" value="#{simpleBean.input}" /> 
> <h:commandLink id="commandLink1" value="Click here to execute 'form a' and 'form b'  but re-render 'form a'"> 
> <f:ajax execute="b :a" render=":a" /> 
> </h:commandLink> 
> </h:form>
> {code}

> The issue is that on MyFaces 2.3.1 the hidden input javax.faces.ViewState is being removed from form "b" after we submit form "a" and viceversa. As a result, cross form submit is not working as expected, you either have to refresh the page before executing submit on the second form or you have to execute submit twice so the update is reflected in the other form.

> I have provided a sample app that shows the issue when MyFaces 2.3.1 is used.
>  # Just deploy the app on Tomcat and drive a request to: [http://localhost:8080/JSF23Spec790/test1.xhtml]
>  # Enter a text in input1 and click submit button next to the input. Check the rendered page.
