    Default Can't get TreePanel example to work; Rendering issue

    Can't get TreePanel example to work; Rendering issue


    Hi,

    I just started using ExtJS I am basically just copying the TreePanel checkbox example but it isn't rendering properly.
    This is the code:
    Code:
    <script type="text/javascript">
    
    	Ext.onReady(function(){
    		Ext.BLANK_IMAGE_URL = 'ext/resources/images/default/s.gif';				
    		
    		var tree = new Ext.tree.TreePanel({
            renderTo:'sidebar',
            title: 'Albums',
            height: 500,
            width: 300,
            useArrows:true,
            autoScroll:true,
            animate:true,
            enableDD:true,
            containerScroll: true,
            rootVisible: false,
            frame: true,
            root: {
                nodeType: 'async'
            },
            
            // auto create TreeLoader
            dataUrl: 'check-nodes.json',
            
            listeners: {
                'checkchange': function(node, checked){
                    if(checked){
                        node.getUI().addClass('complete');
                    }else{
                        node.getUI().removeClass('complete');
                    }
                }
            },
        });
    
        //tree.getRootNode().expand(true);
     
      }); //end onReady
    </script>
    This is the Json file:
    Code:
    [{
        text: 'Me', 
        cls: 'folder',
        children: [{
            id:'Bday 2009',
            text: 'Bday 2009',
            leaf: true,
            checked: false
        },{
            id:'Bday 2010',
            text: 'Bday 2010',
            leaf: true,
            checked: false
        },{
            id:'New Years',
            text: 'New Years',
            leaf: true,
            checked: false
        }]
    },{
        text: 'Friend 1',
        cls: 'folder',
        children: [{
            id:'Cuba trip',
            text: 'Cuba trip',
            leaf: true,
            checked: false
        },{
            id:'Hike',
            text: 'Hike',
            leaf: true,
            checked: false
        },{
            id:'Car ride 2007',
            text: 'Car ride 2007',
            leaf: true,
            checked: false
        }]
    },{
        text: 'Friend 2', 
        cls: 'folder',
        children: [{
            id:'Mountains',
            text: 'Mountains',
            leaf: true,
            checked: false
        }]
    }]
    But the tree is all screwed up (see attached screenshot). There are no errors in firebug. I can't figure out what is going wrong!

    Default ?

    ?


    No one has seen this before?? I was kinda hoping it was a newb mistake since it's such a basic example. I can't find anything else on it though. It almost looks like it might be css problem, any ideas??

    Default


    is the blank_image_url really ext/resources/images/default/s.gif ?

    does extjs resize in /ext of your site?

    That said, do you have any other css that might conflict?
