Joe Crichton commented on MYFACES-4605:
---------------------------------------
Here is a simple two form two button case:
{noformat}
<html xmlns="http://www.w3.org/1999/xhtml";

xmlns:h="http://xmlns.jcp.org/jsf/html";

<meta name="decorator" content="none"/>
<title>Carbon Title</title>
</h:head>
<h:body>
<h:form id="f1">
<h:commandButton value="pushme form 1">
<f:ajax event="click" render=":div2"/>
</h:commandButton>
</h:form>
<div jsf:id="div2">
<h:form id="f2">
<h:commandButton value="pushme form 2">
<f:ajax event="click" render=":f1/>
</h:commandButton>
</h:form>
</div>
</h:body>
</html>
{noformat}
This is what I see in the browser inspect panel ... both forms have the
viewstate present:
{noformat}
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:carbon="http://java.sun.com/jsf/composite/carbon";>
<head id="j_id_2">

<meta http-equiv="Cache-Control" content="no-cache">

<body>
<script type="text/javascript"> myfaces.config._autoeval = true;
</script>
<form id="f1" name="f1" method="post"
action="/technologyconnect/joetest.xhtml"
enctype="application/x-www-form-urlencoded">
<input id="f1:j_id_6" name="f1:j_id_6" type="submit"
value="pushme form 1" onclick="jsf.util.chain(this,
event,'jsf.ajax.request(this,event,{render:\'div2
\',\'jakarta.faces.behavior.event\':\'click\'})'); return false;">
<input type="hidden" name="f1_SUBMIT" value="1">
<input type="hidden" name="jakarta.faces.ViewState"
id="j_id__v_0:jakarta.faces.ViewState:1"
value="OGQ4ZTBlNzJhYWI2NDQ0NTAwMDAwMDA2" autocomplete="off">
</form>
<div id="div2">
<form id="f2" name="f2" method="post"
action="/technologyconnect/joetest.xhtml"
enctype="application/x-www-form-urlencoded">
<input id="f2:j_id_9" name="f2:j_id_9" type="submit"
value="pushme form 1" onclick="jsf.util.chain(this,
event,'jsf.ajax.request(this,event,{render:\'div2
\',\'jakarta.faces.behavior.event\':\'click\'})'); return false;">
<input type="hidden" name="f2_SUBMIT" value="1">
<input type="hidden" name="jakarta.faces.ViewState"
id="j_id__v_0:jakarta.faces.ViewState:2"
value="OGQ4ZTBlNzJhYWI2NDQ0NTAwMDAwMDA2" autocomplete="off">
</form>
</div>
</body>
</html>{noformat}
When I press the first button, this is what I see come back from the post, so
it actually updates j_id__v_0:jakarta.faces.ViewState:1, and does not include
the viewstate in the 2nd form being rendered
{noformat}
<?xml version="1.0" encoding="UTF-8"?><partial-response
id="j_id__v_0"><changes><update id="div2"><![CDATA[<div id="div2"><form id="f2"
name="f2" method="post" action="/technologyconnect/joetest.xhtml"
enctype="application/x-www-form-urlencoded"><input id="f2:j_id_9"
name="f2:j_id_9" type="submit" value="pushme form 1"
onclick="jsf.util.chain(this, event,'jsf.ajax.request(this,event,{render:\'div2
\',\'jakarta.faces.behavior.event\':\'click\'})'); return false;" /><input
type="hidden" name="f2_SUBMIT" value="1" /></form></div>]]></update><update
id="j_id__v_0:jakarta.faces.ViewState:1"><![CDATA[OGQ4ZTBlNzJhYWI2NDQ0NTAwMDAwMDA2]]></update></changes></partial-response>{noformat}
However, after the jsf update completes, the 2nd form DOES have a viewstate
value listed with id of j_id__v_0:jakarta.faces.ViewState:0 (different than
anything seen thus far).
{noformat}
<div id="div2">
<form id="f2" name="f2" method="post"
action="/technologyconnect/joetest.xhtml"
enctype="application/x-www-form-urlencoded">
<input id="f2:j_id_9" name="f2:j_id_9" type="submit" value="pushme form
2" onclick="jsf.util.chain(this,
event,'jsf.ajax.request(this,event,{render:\'f1
\',\'jakarta.faces.behavior.event\':\'click\'})'); return false;">
<input type="hidden" name="f2_SUBMIT" value="1"> <input type="hidden"
id="j_id__v_0:jakarta.faces.ViewState:0" name="jakarta.faces.ViewState"
value="YjFiOGU5ZjFjNmMzNjJkMjAwMDAwMDEx">
</form>
</div>{noformat}
So maybe a wild goose chase (sorry). The original issue was an error case I had
caused during the conversion to Jakarta JSF 3.0 dealing with Omnifaces. When I
fixed my name space issue, the code was working, using the Balusc workaround
for 2nd form viewstate fixup.

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