Strange "alert" when calling grid.LoadXML

Suite and Optimus Suite 5
#1

Hello,

Just today I downloaded DHX and started to read the tutorials. Decided to “expand” the example a bit and added a button in the “ContactForm” which creates a window and attaches a grid to it.

So the user clicks on the button and a new window is displayed along with a “selectGrid” which gives the user the option to select any of the records.

    <script type="text/javascript">
        //Here we'll put the code of the application
		var layout,menu,toolbar,contactsGrid,contactForm,selectGrid,selectToolbar;
		dhtmlx.image_path = "codebase/imgs/";
		
		function doOnRowDblClicked(rowId) {
			return confirm("Row with ID " + rowId + " was double clicked. Do you want to proceed?");
		}
		
		
		dhtmlxEvent(window,"load",function(){
		//application code goes here
		
			
			//layout
			layout = new dhtmlXLayoutObject(document.body,"2U");
			layout.cells("a").setText("Contacts");
			layout.cells("b").setText("Contact Details");
			layout.cells("a").setWidth(600);
			
			menu = layout.attachMenu();
			menu.setIconsPath("codebase/imgs/");
			menu.loadXML("xml/menu.xml");
			
			toolbar = layout.attachToolbar();
			toolbar.setIconsPath("icons/");
			toolbar.loadXML("xml/toolbar.xml");
			
			contactsGrid = layout.cells("a").attachGrid();
			//contactGrid.setImagePath("./codebase/imgs/");
			//contactGrid.setSkin("dhx_skyblue");
			contactsGrid.setHeader("ID,Name,Last Name,Email");
			contactsGrid.setInitWidths("50,100,100,*");
			contactsGrid.setColAlign("left,left,left,left");
			contactsGrid.setColTypes("ro,ro,ro,ro");
			contactsGrid.setColSorting("int,str,str,str");
			contactsGrid.init();
			
			contactsGrid.attachHeader("#numeric_filter,#text_filter,#text_filter,#text_filter");
			contactsGrid.load("xml/contacts.php");
			
			contactForm = layout.cells("b").attachForm();
			contactForm.loadStruct("xml/form.xml");
			
			contactForm.attachEvent("onButtonClick", function(name, command){
				// any custom logic here
				
				var dhxWins= new dhtmlXWindows();
				dhxWins.enableAutoViewport(true);
				dhxWins.createWindow("w_departments", 100, 100, 500, 500);
				dhxWins.window("w_departments").setText("Departments");
				dhxWins.window("w_departments").centerOnScreen();
				
				selectToolbar = dhxWins.window("w_departments").attachToolbar();
				selectToolbar.loadXML("xml/selection_toolbar.xml");
				
				selectGrid = dhxWins.window("w_departments").attachGrid();
				selectGrid.attachEvent("onRowDblClicked", doOnRowDblClicked);
				selectGrid.loadXML("xml/tab_departments.xml");
				
				
				
			});
			
			contactsGrid.attachEvent("onRowSelect", function(rID,cInd){
				contactForm.load("./xml/contact_details.php?id="+rID);
			})
			
			var dpf = new dataProcessor("xml/contact_details.php");
			dpf.init(contactForm);
			
			
			dpf.attachEvent("onAfterUpdate",function(sid,action,tid,xml_node){
				contactsGrid.cells(sid,1).setValue(contactForm.getItemValue("pname"));
				contactsGrid.cells(sid,2).setValue(contactForm.getItemValue("psurname"));
				contactsGrid.cells(sid,3).setValue(contactForm.getItemValue("email"));
			})
		})
    </script>

Checked how to initialize a grid and that’s how I made the tab_departments.xml

    <rows> 
        <head>
			<beforeinit></beforeinit>
			<afterInit> 
                    <call command="load"><param>xml/tab_departments.php</param></call> 
            </afterInit> 
            <column width="20" type="ro" align="center" color="white" sort="str">ID</column>  
            <column width="80" type="ro" align="left" sort="str">Description</column>
                    
            <settings> 
                    <colwidth>%</colwidth> 
            </settings> 
        </head> 
    </rows>

It seems to be working fine with one minor glitch:
After I click “OK” , data is displayed perfectly, but I cannot understand where this alert comes from.

That’s the result after i click OK

Thank you

I found “firebug” and thought to give it a try too.

Here is what i get after selectGrid.LoadXML runs

docObj is null
http://192.168.1.142/codebase/dhtmlx.js
Line 68

if (docObj.nodeName.indexOf("docum...=XPathResult.FIRST_ORDERED_NODE_TYPE etc.etc.

In case of FireFox the problem can be caused by any whitespace before <?xml declaraton (the declaration must be the first text in the output).

Also, please, check that the Content-type is correct - text/xml.

Thank you very much for your reply.

I configured apache mime.types to send correct header but I still have the same problem.

I followed the example and made an XML file like this:

<?xml version="1.0"?>
<rows> 
        <head>
	    <beforeinit></beforeinit>
	    <afterInit> 
                    <call command="load"><param>xml/tab_departments.php</param></call> 
            </afterInit> 
            <column width="20" type="ro" align="center" color="white" sort="str">ID</column>  
            <column width="80" type="ro" align="left" sort="str">Description</column>
                    
            <settings> 
                    <colwidth>%</colwidth> 
            </settings> 
        </head> 
</rows>

Could it be that I don’t have any actual DATA inside the XML file?

Try to open gerenated xml in the browser. If xml isn’t correct browser should point you to problem.
