Summary: Regression in Spec Issue 790: Cross form submit
Key: MYFACES-4229
URL: https://issues.apache.org/jira/browse/MYFACES-4229
Project: MyFaces Core
Issue Type: Task
Components: JSR-372
Affects Versions: 2.3.1
Reporter: Eduardo Breijo
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 the we submit form "a" and viceversa.
