JSF TreeMap Iteration Problem Using JSTL In XHTML

[VijayAnand Venkateswaran]

Dear All,
I have a Map[key,value] In My Action Class.Now I try to print the key followed by corresponding values In My XHTML Page Using JSTL 1.2 ,JSF 1.2.
The Below Snippet Does not print AnyThing. I had tested in My Action Class by printing Map's Size its not empty.In the beforePhase event i call a method that sets value to the Map.

 
<c:forEach value="#{ReportGeneratorActionBean.displayMap}" var="test" >
	  <tr>
	    <h:outputText value="#{test.key}"/>
	    <h:outputText value="#{ReportGeneratorActionBean.displayMap[instNo]}"/>
	    <h:outputText value="#{ReportGeneratorActionBean.displayMap.instNo}"/>
	    <h:outputText value="#{displayMap[clgDate]}"/>
	    <h:outputText value="#{displayMap.depdate}"/>
	     <h:outputText value="#{ReportGeneratorActionBean.displayMap['AGRA'].depslipno}"/>
	    <h:outputText value="#{test}"/>
          </tr
></c:forEach>
 

Where as when i try to print Map As it is All the key & Values Of Map gets Printed.

   <c:forEach value="#{ReportGeneratorActionBean.displayMap}" var="test" >
	  <tr>
	      <h:outputText value="#{ReportGeneratorActionBean.displayMap]}"/>
	      </tr>
</c:forEach>
    

What I Want to Do In My xhtml Page Is :

KEY:
      VALUE1
      VALUE2
      VALUE3   
 

The Same I achieved In My Plain Jsp Page By doing like this..

  
<c:forEach items="${displayMap}" var="map">
		<tr>
			<td  ><c:out value="${map.key}"></c:out></td>
		</tr>
		<c:forEach items="${map.key}">
		<c:set var="totalAmt" value="0"></c:set>
				<c:forEach items="${map.value}" var="list" varStatus="index">
					   
					   <tr>
						<td><c:out value="${list.global_srno}"></c:out></td>
						<td><c:out value="${list.depslipno}"></c:out></td>
						<td><c:out value="${list.clgDate}"></c:out></td>
						<td><c:out value="${list.depdate}"></c:out></td>
						<td ><c:out value="${list.instNo}"></c:out></td>
						<td ><c:out value="${list.retInstAmt}"></c:out></td>
						<td ><c:out value="${list.recoveredAmt}"></c:out></td>
                                      </c:forEach>
                           </c:forEach>
                </c:forEach>

  

Is it Possible to the Same Type Of Stuff In JSF Or Not??
Please Help Me.

JSF has actual menu and tree tags to do that. Not in the core tagset, but in the various extensions like Tomahawk, RichFaces, IceFaces, and so forth.

As a general rule, you shouldn't put JSTL tags in a JSF view. You shouldn't have to. And in the case where you're actually putting logic JSTL in the view, you shouldn't. Period. It violates MVC.

Dear Tim,
Thanks for the Reply.I am aware of the Fact that i am Violating MVC,but from the requirement perspective i want to Know its possible or not with JSTL AND JSF,because i achived it using Plain JSP.

Well, if you tried, you could probably intermix COBOL code in with JSF. But just because you can do something doesn't mean it's a good idea.

Every framework tends to influence the shape of its projects. Good frameworks are flexible enough that the end user can't tell which framework is actually being used, and JSF is fairly good about that (except for the URL issues).
