Alexander Smirnov commented on RF-8499:
---------------------------------------

Yes, this is a well known problem, In some browsers documents.forms collection does not updated on DOM changes.
The a4j:form is a workaround that has been invented the most for such case.

>                 URL: https://jira.jboss.org/jira/browse/RF-8499
>             Project: RichFaces
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 3.3.2.SR1
>            Reporter: Martin Frey

> If you have a <rich:panel> which includes a <h:form> element the reference in the "document.forms" in Javascript is lost if something calls reRender for this panel. The form stops working after reRender because document.forms contains an undefined entry instead of the newly rendered form.
> Here's a samplecode that shows the problem:
> <ui:composition xmlns="http://www.w3.org/1999/xhtml"
> 	xmlns:ui="http://java.sun.com/jsf/facelets"
> 	xmlns:h="http://java.sun.com/jsf/html"
> 	xmlns:f="http://java.sun.com/jsf/core"
> 	xmlns:a="http://richfaces.org/a4j"
> 	xmlns:rich="http://richfaces.org/rich">
> 	<h:form>
> 		<h:commandLink action="#{bean.someAction}" value="Action" />
> 	</h:form>
> 	<a:form>
> 		<a:commandLink value="refresh" reRender="panel1" />
> 	</a:form>
> 	<rich:panel styleClass="panel" id="panel1">
> 		<f:facet name="header">Panel</f:facet>
> 		<h:form>
> 			<h:commandLink action="#{bean.someAction}" value="Action" />
> 		</h:form>
> 		<a:form>
> 			<a:commandLink action="#{bean.someAction}" value="Action" />
> 		</a:form>
> 	</rich:panel>
> </ui:composition>
