A strange display bug with CFHTTP?

I have a report that is created within a CFLOOP over a list of integers. For each list element, a new report row is produced. Simple, and it works fine.

However, I'm having an intermittent display issue I can't figure out. Only periodically, for the same set of data, if I refresh the report screen I see the display of the last list element in the CFLOOP, e.g. "14" over the report on the screen. Hit refresh a few times it goes away. Some more refreshes and it comes back. At first I thought it was just a missed or unclosed CFOUTPUT, but no luck.

I've traced it so that it only displays that last list element in the CFLOOP. I created a smaller version of the code just for testing. Here is the CFLOOP statement: <cfloop list="10,14" index="ListItem">  Full code is at the bottom of this post.

Here is the output after several refreshes (this is correct).

Start loop for listitem:10
  inner loop index=1
  inner loop index=2
endloop

Start loop for listitem:14
  inner loop index=1
  inner loop index=2
endloop

And sometimes if I refresh, I get this output (note the 14, the last element in the CFLOOP list)

Start loop for listitem:10
  inner loop index=1
  inner loop index=2
endloop

Start loop for listitem:14
14   inner loop index=1
  inner loop index=2
endloop

Again, that 14 only appears intermittenty. Inside my loop is a CFHTTP statement. If I comment out this statement, the '14' goes away, but obviously I need that statement. Just trying to track down the issue.

Here's my test code that produced the output above:

<cfloop list="10,14" index="ListItem">
 

          Start loop for listitem:<cfoutput>#ListItem#</cfoutput> <br />

        <cfobject component="#application.CFCPath#components.cGroup" name="clientObj">
        <cfset ClientGroupInfo = clientObj.ServicePowerInfo(ListItem)>
        <cfset ClientGroupDesc = clientObj.getClientGroupInfo(ListItem)>
   
        <cfset ClientGroupCurrent = ClientGroupDesc.CompanyName>
   
        <cfset form.runsheetdate = Now()>

        <cfsavecontent variable="my_xml">
            <dispatch>
              <request>
                <userID><cfoutput>#ClientGroupInfo["username"]#</cfoutput></userID>
                <companyID><cfoutput>#ClientGroupInfo["companyid"]#</cfoutput></companyID>
                <date><cfoutput>#DateFormat(form.runsheetdate,"YYYY-MM-DD")#</cfoutput></date>
              </request>
            </dispatch>
        </cfsavecontent>
       
        <cfset xml_obj = xmlparse(my_xml)>
        <cfset webSvcURL = "http://test/test.aspx">

       <cfhttp url="#webSvcURL#" charset="utf-8" method="post"  ><cfhttpparam type="xml" value="#my_xml#"></cfhttp>

        <cfloop index="i" from="1" to="2">
          inner loop index=<cfoutput>#i#</cfoutput><br />
        </cfloop>
  endloop<br /><br />

</cfloop>

Any ideas are welcome!
