A4JSF only works once on the site...
Hello,
First at all: I use Richfaces 3.1.0 RC3
I've used quite a lot a4j features in my site, and I never had any major problems. But now I have a problem that I can't solve and I don't know if it's an a4j-bug or if it's a problem from my side...
The problem is, that I have a simple site, with an h:selectOneMenu. The first problem was the a4j:support (for the selectOneMenu) didn't always sent the data on the "onchange" event. I solved this by using a4j:jsFunction (and removing a4j:support)...
The user can select something in this menu, and after he selected an item, a part of the site is reloaded with a4j (I use jsp:include to include other parts when the user selects an item). And there's the problem. I have some a4j stuff in my included pages (well, buttons and some input-fields). When I click an button, the method from the bean is called. But when I click another (or the same) button again, nothing happens. I've checked if the bean is still in the session-scope, but everything seems fine there. Even the post-command is the same.
Here's the code:
<f:view locale="#{LoginBean.language}">
<f:loadBundle basename="com.ios.web.properties.MessageResources"
var="msg" />
<h:form>
<a4j:region>
<a4j:jsFunction name="armSelected" reRender="servicearmdata"
ajaxSingle="true" status="genajaxloading">
<a4j:actionparam name="selectedArm"
assignTo="#{processBowlModuleService.selectedTab}"></a4j:actionparam>
</a4j:jsFunction>
<h:selectOneMenu styleClass="inputtextclass"
value="#{processBowlModuleService.selectedTab}"
onchange="armSelected(this[this.selectedIndex].value);">
<f:selectItems value="#{processBowlModuleService.armItems}" />
</h:selectOneMenu>
<h:panelGrid border="1" id="servicearmdata"
styleClass="panelgridcontent">
<%
com.ios.web.beans.ProcessBowlModuleService myBean = (com.ios.web.beans.ProcessBowlModuleService) session
.getAttribute("processBowlModuleService");
String includePage = "../include/servicearms/"
+ myBean.getArmIncludeName() + ".inc.jsp";
%>
<jsp:include page="<%= includePage %>" />
</h:panelGrid>
<jsp:include page="/include/genajaxloading.inc.jsp" />
</a4j:region>
</h:form>
<jsp:include page="/include/errorpanel.inc.jsp" />
<a4j:outputPanel id="hiddenerrorinformation" ajaxRendered="true">
<h:inputHidden id="errorid" value="#{LoginBean.state}" />
<h:inputHidden id="errormsg" value="#{LoginBean.errorMsg}" />
</a4j:outputPanel>
</f:view>
