Question

Is it possible to reuse a form in two different views in JSF? I know about the ui:include but how would you do it with the action on the submit button for example? Or do I need to duplicate the forms?

Answer 1

When using <ui:include> you can parameterize the bean and/or the method by <ui:param>.

<ui:include src="...">
  <ui:param name="bean" value="#{someBeanName}" />
  <ui:param name="action" value="someMethodName" />
</ui:include>

with

<h:commandButton ... action="#{someBeanName[someMethodName]}" />

You can also make it a Facelets tag file instead so that you end up with something like

<my:someForm bean="#{someBeanName}" action="someMethodName" />

A composite component is also doable, but IMO not really the right approach for this purpose.
