Still having navigation problems and need help with how to debug

Question

Hi,
I've been porting over a servlet project to JSF and I'm still having navigation problems. I thought the problem might have been because the original project used HTML frames and so the "from-view-id" JSP defined the frame/framesets and the specific JSP that does the submit (and so is named in the "from-view-id" is never defined in a "to-view-id" attribute). I've now switched to using an IFRAME, and that resolves that problem. So now the JSP is defined in a "to-view-id" attribute and it includes an named IFRAME that can be used as a target. I press the submit button and I get not the JSP expected butinstead the same JSP displayed inside its own IFRAME.
Here is the code for the submit. I've simplified it as much as possible with a static action (originally it was a call to a method) just to try and get things to work. This is the current version:
<h:commandButton value="View Alias" action="foo" styleClass="select" type="submit" />Here is the navigation rule in faces-config.xml. Again, the problem is that SelectManager get redisplayed in the IFRAME instead of display.jsp.
<navigation-rule>
   <from-view-id>/SelectManager.jsp</from-view-id>
   <navigation-case>
      <from-outcome>foo</from-outcome>
      <to-view-id>/display.jsp</to-view-id>
   </navigation-case>
</navigation-rule>I have also tried it without the "from-outcome-value" which I presume means that the "to-view-id" gets displayed unconditionally and it still fails. Any ideas on how I can debug this? (I'm using GlassFish if that's important to know)

Raymond, The real trick is avoid doing technical things when coming down with the flu (I should also add that I'm a JSF newbie). Reading your original message this time I see what you're suggesting and found a conversion error although I don't understand it. Here's the code (including the <h:message/>):
            <h:selectOneMenu value="#{members.dcodes}"
              style="color: #7f0000" id="selector">
              <f:selectItems value="#{members.departmentList}" />
            </h:selectOneMenu> 
            <h:message for="selector" style="color:white"/>And here's a snippet of the generated HTML:
<select id="j_id_id26:selector" name="j_id_id26:selector" size="1" style="color: #7f0000">
         <option value="aad" selected="selected">Academic Advising</option>
     <option value="aaf">Academic Affairs</option>
     <option value="adm">Admission</option>
     <option value="up">Upward Bound</option>
</select>If I select "Admission" for example, the error I get is:
Conversion Error setting value 'adm' for 'null Converter'.Since everything is a String value, I don't get the error. Could someone please enlighten me.
Thanks.
