Thanks Andrew i fixed it. I have similar kind of problem in different
situation
Their is a Search Form . Click on Search button reRenders the h:dataTable to
display the search resultSet but this happens only after clicking the
Search button twice or thrice. Quite wierd
I tried doing the same fix but it didnt work i.e.
<a4j:region>
<h:commandButton id="search" value="Search" styleClass="button" >
<a4j:support event="onclick" action="#{searchDeviceBean.search}"
reRender="searchpanel" ajaxSingle="true"/>
</h:commandButton>
</a4j:region>
<a4j:outputPanel id="searchpanel"
rendered="#{searchDeviceBean.searchResultSet}">
<h:dataTable id="searchResults" value="#{searchDeviceBean.queryResults}"
var="resultSet" styleClass="list" rowClasses="odd,even" >
<h:column/>
</h:dataTable>
</a4j:outputPanel>
Any pointers/suggestions will be highly appreciated
