Hi,

page code:
<h:form>
<a4j:jsFunction name="updateNextView" reRender="nextView">
<a4j:actionparam name="param1" assignTo="#{nav.nextView}"/>
</a4j:jsFunction>
<a4j:jsFunction name="rerendSelf" reRender="#{nav.rerendedComp}">
<a4j:actionparam name="param2" assignTo="#{nav.rerendedComp}"/>
</a4j:jsFunction>
<a4j:jsFunction name="rerendBefore" reRender="#{nav.rerendedOldComp}"/>
</h:from>
......
<ui:composition>
<h:panelGrid id="resourceNav">
<h:outputLink value="javascript:;">
<span class="#{nav.nextView=='resource_m_select'?'navTextActive':'navText'}"
onmousemove="this.className='navTextActive'"
onmouseout="this.className='#{nav.nextView=='resource_m_select'?'navTextActive':'navText'}'"
onclick="updateNextView('resource_m_select'),rerendSelf('resourceNav'),rerendBefore()">manage<span>
</h:outputLink>
<h:outputLink value="javascript:;">
<span class="#{nav.nextView=='resource_m_add'?'navTextActive':'navText'}"
onmousemove="this.className='navTextActive'"
onmouseout="this.className='#{nav.nextView=='resource_m_add'?'navTextActive':'navText'}'"
onclick="updateNextView('resource_m_add'),rerendSelf('resourceNav'),rerendBefore()">add</span>
</h:outputLink>
</h:panelGrid>
</ui:composition>It's like a navigation link list,being selected or not,the style are different.
This Exception appears when first time click one of the link,then it will not appear.
