loadXML(xml, aftercall) - still cannot access tree elements

I’m having trouble accessing tree elements immediately after loading the tree. But if I put an alert right after the load, then everything works fine. So this alludes to an issue with hitting the tree before it finishes loading. My code is below…please advise.



var globalFieldName = “”;

        var globalTree = “”;        

        

        function retrieveMetaValues(fieldName, xmlName) {

            var gpreField = document.getElementById(fieldName);

            var gpreValue = gpreField.value;

            globalFieldName = fieldName; //using global var because I cannot pass vars with loadXML() method

            

            if (gpreValue != ‘’ && gpreValue.length != 0) {                

                var newdiv = document.createElement(“div”);

                newdiv.innerHTML = “

”;

                gpreField.appendChild(newdiv);            

                

                globalTree=new dhtmlXTreeObject(“treebox_tree”,“100%”,“100%”,0);

                globalTree.loadXML(’/icons_root/extensions/pw/xml/’ + xmlName + ‘.xml’, searchTree());                

            }

        }

        

        // Hits XML to retrieve labels for each codes

        function searchTree() {

            

            //alert('state = ’ + globalTree.getXMLState()); //if this line is uncommented, everything works fine!!!

            var fieldName = globalFieldName;

            var gpreField = document.getElementById(fieldName);

            var gpreValue = gpreField.value;                

            

            var splitString = gpreValue.split(",");

            var textString = “”;            

            for(var i = 0; i < splitString.length; i++) {                

                textString = textString + globalTree.getItemText(splitString[i]) + ‘\n’;

            }                

            

            var metaField = document.getElementById(fieldName + ‘_TREE’);

            metaField.value = textString; //put text into visible fields            

        }

Please, try to use the following approach to set afterCall function:


globalTree.loadXML(’/icons_root/extensions/pw/xml/’ + xmlName + ‘.xml’, searchTree);


instead of


globalTree.loadXML(’/icons_root/extensions/pw/xml/’ + xmlName + ‘.xml’, searchTree());
