@Pavol,
Taking your example, I added a servlet filter. I think I see what is wrong.
{code}
10:34:17,724 INFO [stdout] example=example&=button&javax.faces.ViewState=-2621112732722648039%3A-4544027983878449135&javax.faces.source=example%3Aj_idt5&javax.faces.partial.event=click&javax.faces.partial.execute=example%3Aj_idt5%20example%3Aj_idt5&javax.faces.behavior.event=action&javax.faces.partial.ajax=true
{code}
Specifically notice the "&=button" which I don't believe is correct syntax. If I add name="foo" on the button the post looks better.
{code}
10:36:36,074 INFO [stdout] example=example&foo=button&javax.faces.ViewState=8332388767031820036%3A3512517802181868303&javax.faces.source=example%3Aj_idt5&javax.faces.partial.event=click&javax.faces.partial.execute=example%3Aj_idt5%20example%3Aj_idt5&javax.faces.behavior.event=action&javax.faces.partial.ajax=true
{code}
Since your example does not have any RichFaces tags I will update the Majarra JIRA (http://java.net/jira/browse/JAVASERVERFACES-2666). Thanks for your help.

> I was surprised that this was only an IE7 issue, but I did find that PrimeFaces ran into a similar problem (http://code.google.com/p/primefaces/issues/detail?id=4361).
> Is there a workaround for this? Is this a Mojarra, RichFaces, or JBoss issue?
> I created http://java.net/jira/browse/JAVASERVERFACES-2666 in case this is a Mojarra problem, maybe we could help them resolve the issue.
