I have a page that looks something like this:

<h: form>
// lot of fields
<a4j:commandButton type="button" action="#{contactNavigation.reset}" reRender="addcontact-view" oncomplete="Richfaces.showModalPanel('addContactPanel');" styleClass="button" value="#{msg.addContact}" />
// rest of the form
</h:form>

Then, at the bottom of the jsp i have a ModalPanel included this way:
<a4j:include id="addcontact-panel" viewId="addContact.jsp" />

The modalPanel contains its own h:form (external respect to the previuos h:form)
The problem is that when i submit the form inside the modalPanel, errors are displayed in the first form, not in the modalPanel (both forms include a rich:messages). Although errors are displayed correctly i don't want them to be displayed is such a way. Each form should intercept only its own errors. Any ideas?

regards
