"HttpParam is undefined" JS error when using dynamic container in portal

Question

I am using dynamic container tag "*dc:container*" within an iterator in a pageflow portlet & I'm sending different parameter in each iteration, it worked well in IE7, but in FireFox, some of the rows were rendered & for the rest I received the following exception:
DynamicContentXmlHttpServlet: Error dispatching request to requested action: '/src/com/loadFriendRatePlan'.
java.lang.NullPointerException

Note: every time i refresh the page different rows are rendered, which means that the non rendered rows have nothing to do with the parameter sent in each iteration.
I've added the portlet to portal, & now nothing is rendered in both IE7 & FireFox, & "HttpParam is undefined" JavaScript error is displayed in both browsers.
Note : my portlet "Async Content rendering" property is set to ajax, & the portal "Asynchronous Model" property to enabled.
<h3>Here's sample of my tag code:</h3>
<dc:executeContainerAction action="loadFriendRatePlan" dcContainerId="${container.index}"
     var="ratePlan"/>           
<dc:container dcContainerId="${container.index}">     
     <dc:containerActionScript action="loadFriendRatePlan" initial="true"
          onErrorCallback="displayMessageNotAvailable">
          <dc:containerActionParam name="friendAccount" value="${container.item.accountNumber}"/>
          <dc:containerActionParam name="friendContractType" value="${container.item.contractType}"/>                         
     </dc:containerActionScript>
</dc:container>
<script type="text/javascript">
     ${ratePlan}
</script>
Any clue how can I solve both errors?

Just so there is a record of this on the Adobe site...
IF you are running Apache and have virtual hosts, be sure to add the line
Alias /CFIDE "c:/inetpub/wwwroot/CFIDE"
to the virtual host list. Of course change the path c:/inetpub/wwwroot/CFIDE" to whatever is set up in the CF Administrator.
Otherwise, none of your cfform stuff will work properly, AJAX will croak,  and you will get a 'Coldfusion' is undefined error.
