Werner Punz commented on MYFACES-4605:
--------------------------------------
Mhh I tried it in my integration testsuite by altering my multiform test:
{code:java}
// code placeholder
<h:form id="firstForm" prependId="false">
<h:panelGroup layout="block" id="renderTarget1"/>
<h:inputText id="first_input" value="#{multiFormBean.inputText1}"/>
<h:commandButton id="click1" action="#{multiFormBean.doSubmit1}"
value="submit1"
onclick="javascript:jsf.ajax.request(this, event,
{execute:'firstForm', render:'panel2'}); return false;">
</h:commandButton>
</h:form>
</h:panelGroup>
<h:panelGroup id="panel2">
<h:form id="secondForm" prependId="false">
<h:panelGroup layout="block" id="renderTarget2"/>
<h:inputText id="second_input" value="#{multiFormBean.inputText2}"/>
<h:commandButton id="click2" action="#{multiFormBean.doSubmit2}"
value="submit2"
onclick="javascript:jsf.ajax.request(this, event,
{execute:'firstForm', render:'panel1'}); return false;">
</h:commandButton>
</h:form> {code}
The test runs 100 times an alternative click either click1 or click2
and then processes the ajax response:
!image-2023-06-20-21-22-50-593.png|width=661,height=159!
In the end I am getting a properly updated viewstate which is identical on both
forms.
The behavor looks correct to me! I also walked through the code, the viewstate
of the executing form is updated as well as the viewstate of the forms in the
render area.
This is correct behavior, as per spec!

> Using openliberty with jsf-3.0 feature still has this occurring. Using the
