I don't want to specify the url for a (tree, form etc) element at load time but instead I want to set it during run time.
The problem is, if I don't define the url at load time, or if I define it as empty string or null, then the load method will not work:
$('#xx').combobox({
onSelect:function(rec){
var url = '/vwltsa/?_func=xxx;
$('#yy').datagrid('load',url);
}
});
$('#emplt').datagrid({
url:null,
onLoadSuccess: function(){
cl('loaded');
}
