Error using Javascript

[Bluesangig]

Hi all,

I am trying to append a TABLE element (being created dynamically) to an existing DIV element in a HTML document. But when trying to do so it is giving me the following error:

Line: 141
Char: 5
Error: Unexpected call to method or property access.
Code: 0
URL: http://localhost:8080/TreeViewer/tree_dyna_data.jsp

The javascript that I used for doing this task is as follows:

function addChildNode(httpRequest,node)
{
    if(httpRequest.readyState == 4){
        if(httpRequest.status == 200){
            var xmlText = httpRequest.responseText;
            var xmlDom = getXmlDocument(xmlText);
            var error = xmlDom.getElementsByTagName("error").item(0);
            if(error==null){
                alert("in addChildNode()");
                var theDiv = node.nextSibling;
                theDiv.style.display="block";
                alert(theDiv.style.display);
                var theTable = document.createElement("table");
                var theTbody = document.createElement("tbody");    
 
                //Code that will retrieve the list of file names that are returned from the server and adds them to this node.
                var fileList = xmlDom.getElementsByTagName('F');
                for(var i=0;i<fileList.length;i++){
                    var theRow = document.createElement("tr");
                    var fileType = fileList[i].childNodes[2].firstChild.nodeValue;
                    var theTypeCell= document.createElement("td");
                    theTypeCell.innerHTML="<input type=\"hidden\" value=\""+fileList[i].childNodes[2].firstChild.nodeValue+"\"></input>";
                    var thePathCell = document.createElement("td");
                    thePathCell.innerHTML="<input type=\"hidden\" value=\""+fileList[i].childNodes[0].firstChild.nodeValue+"\"></input>";
                    var theCell = document.createElement("td");    
                    if(fileType=="directory"){
                        theCell.innerHTML="<a onclick=\"Toggle(this)\"><img src=\"img/plus.gif\">&nbsp;"+fileList[i].childNodes[1].firstChild.nodeValue+"&nbsp;</a><div style='display:none'></div>";
                    }else{                
                        theCell.innerHTML="<a onclick=\"Toggle(this)\"><img src=\"img/dot.gif\">&nbsp;"+fileList[i].childNodes[1].firstChild.nodeValue+"&nbsp;</a><div style='display:none'></div>";
                    }
                    theRow.appendChild(theTypeCell);
                    theRow.appendChild(thePathCell);
                    theRow.appendChild(theCell);
                    theTbody.appendChild(theRow);
                }                            
                theTable.appendChild(theTbody);                                                    alert("DEBUG-1");
                                                                theDiv.appendChild(theTable);
                                                                alert(theDiv.nodeType);
                var prevImg = node.firstChild;
                prevImg.src="img/minus.gif";
            }else {
                alert(error.firstChild.nodeValue);
            }
        }else{
            alert("There is some problem with the request");
        }
    }else{        
    }
}

What went wrong in this code. I am clueless. I could only find that the second alert statement that is in bold is not being reached. It is executing all the code till the alert("DEBUG-1"); statement.

Any help regarding this will be verymuch helpful.

Thanks in advance,
Bluesangig
