Hi
I'm using modalPanel with tiles like this :

<rich:modalPanel id="topicPopup" >
 <tiles:insert definition="modalPopupTemplate" flush="false">
 <tiles:put name="body" value="/depStaffMngr/editTopic.jsp"/>
 <tiles:put name="panelID" value="topicPopup"/>
 <tiles:put name="header" value="Edit topic details"/>
 </tiles:insert>
</rich:modalPanel>

modalPopupTemplate defined as :

<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>
<%@ taglib prefix="tiles" uri="http://struts.apache.org/tags-tiles"%>
<%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%>
<%@ taglib uri="http://richfaces.ajax4jsf.org/rich" prefix="rich"%>


 <f:facet name="header">
 <f:verbatim>
 <tiles:getAsString name="header"/>
 </f:verbatim>
 </f:facet>
 <f:facet name="controls">
 <t:div>
 <t:graphicImage value='#{requestScope["basePath"]}img/closed.jpg' style="cursor:pointer" onclick="closePopupObj(this)"/>
 <f:verbatim>
<span style="display:none"><tiles:getAsString name="panelID"/></span>
 </f:verbatim>

 </t:div>
 </f:facet>
 <h:form>
 <a4j:outputPanel ajaxRendered="true">
 <h:messages id="errorMessages" styleClass="error" />
 </a4j:outputPanel>

<tiles:insert attribute="body" flush="false" />
</h:form>

and editTopic.jsp :

<%@ page language="java" pageEncoding="UTF-8"%>


<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>

<f:loadBundle basename="com.unilims.academic.MessageResources" var="msg"/>

<f:subview id="EditTopicView" >

 <h:inputHidden id="id" value="#{topicBean.obj.id}" />

<h:panelGrid columns="2" styleClass="infoTable">
 <f:facet name="header">
 <h:outputText value="Topic details"/>
 </f:facet>
 <h:outputText value="Topic"/> <h:inputText value="#{topicBean.obj.topic}"/>
</h:panelGrid>


<a4j:commandButton value="#{msg['save']}" action="#{topicBean.saveObject}"
oncomplete="closePopup('topicPopup',true)"/>



 </f:subview>

My problems are :
1. modalPanel is not opened unless i open log window
2. i get js error "Prototype.Browser.IE" is null or not an object

debug window log is :
