Ok, I have clearly missed something. At present my code looks like this...
<script type="text/javascript" src="/js/DP_RequestPool.js"></script> <script language="javascript"> myRequestPool = new DP_RequestPool().startInterval(100); function getMinSale(rowNum) { var tempURL = 'http://127.0.0.1/cfc/calculators.cfc?method=minPriceCalc&productgroupid=2&c ostprice=2'; var myRequest = new DP_Request("GET", tempURL, null, updateMinSale, [rowNum]); myRequestPool.addRequest(myRequest); }; function updateMinSale(result, rowNum) { document.getElementById("min" + rowNum).value = 'Done'; }; </script> As you can see I am just setting the cell to 'Done' for now, will worry about the WDDX later. Unfortunately the cell value is not being set. If I copy the line document.getElementById("min" + rowNum).value = 'Done'; to the bottom of the getMinSale() function then the cell value is set so that function is clearly being called but the updateMinSale() is apparently not. If I copy/paste the url from tempURL into my browser window a value is returned so it isn't a timeout issue. Any idea what I have left out? -- Jay No virus found in this outgoing message.
