Description

The issue was initially reported against RichFaces: https://issues.jboss.org/browse/RF-13025
But it does not look like it is anything wrong with RichFaces here.
The issue is reproducible with pure myfaces when partial state saving is turned OFF e.g. with the following code (every second click on "Toggle" button causes new UIOutput element to be inserted to the view tree):

  <h:form>
    <h:commandButton value="Toggle" action="#{bean.togglePanelShown}">
      <f:ajax execute="@this" render="group"/>
    </h:commandButton>
    <h:panelGroup id="group">
      <c:if test="#{bean.panelShown}">
        <!-- Any component with @ResourceDependency annotation. -->
        <custom:componentWithResourceDependency/>
      </c:if>
    </h:panelGroup>
  </h:form>
