Problem with Ext.direct + Ext.tree

paramsAsHash: Boolean
Only used when using directFn. Send parameters as a collection of named arguments (defaults to false). Providing a paramOrder nullifies this configuration.
\r

requestData : function(node, callback, scope){ if(this.fireEvent("beforeload", this, node, callback) !== false){ if(this.directFn){ var args = this.getParams(node); args.push(this.processDirectResponse.createDelegate(this, [{callback: callback, node: node, scope: scope}], true)); this.directFn.apply(window, args); } ... } ... getParams: function(node){ var bp = Ext.apply({}, this.baseParams), np = this.nodeParameter, po = this.paramOrder; np && (bp[ np ] = node.id); if(this.directFn){ var buf = [node.id]; ... if(this.paramsAsHash){ buf = [bp]; } return buf; ... } 

To pass extra parameters, an event handler may be attached to the "beforeload" event, and the parameters specified in the TreeLoader''s baseParams property.
