Hi, I have this problem with XmlTreeLoader with ext js 2.2.1 ... the firebug error is
sp is undefined
[IMG]chrome://firebug/content/blank.gif[/IMG]Ext={version:"2.2.1"};window["undefined"...strain(i.left,i.right);return this}})();
and the code is :
Ext.app.BookLoader = Ext.extend(Ext.ux.XmlTreeLoader, {
processAttributes : function(attr){
if(attr.first){
attr.text = attr.first + ' ' + attr.last;
attr.iconCls = 'author-' + attr.gender;
attr.loaded = true;
}
else if(attr.title){
attr.text = attr.title + ' (' + attr.published + ')';
attr.iconCls = 'book';
attr.leaf = true;
}
}
});
Ext.onReady(function(){
var layoutPanel = new Ext.Panel({
layout:'border',
renderTo: 'div_layout',
defaults: {
collapsible: true,
split: true,
bodyStyle: 'padding:15px'
},
items: [generarArbolDocumentos(),{
title: 'Descripcion del concepto',
collapsible: false,
region:'center',
margins: '5 0 0 0',
contentEl: 'div_contenidos'
}]
});
viewport = new Ext.Viewport({
autoshow:true,
layout: 'fit',
defaults: {
activeItem: 0
},
items: layoutPanel
});
viewport.doLayout();
});
function generarArbolDocumentos(){
var panel = new Ext.Panel({
title: 'Arbol de conceptos',
region:'west',
margins: '5 0 0 0',
cmargins: '5 5 0 0',
renderTo: 'div_arbol',
width: 175,
autoScroll: true,
rootVisible: false,
root: new Ext.tree.AsyncTreeNode(),
loader: new Ext.app.BookLoader({
dataUrl:'visConceptosAjax.jsp?opcion=1'
}),
listeners: {
'render': function(tp){
tp.getSelectionModel().on('selectionchange', function(tree, node){
var el = Ext.getCmp('details-panel').body;
if(node.leaf){
tpl.overwrite(el, node.attributes);
}else{
el.update(detailsText);
}
})
}
}
});
return panel;
}
I just want to load a XML data from a jsp page with parameter "opcion=1" there is the answer:
