working on extjs on rails for tree structure  
when creating a node, no value should be returned to the json  
its giving an alert of the return value

def additem  
@return\_val = Tree.new(:parent\_id=\>params[:parentID],:node\_name=\>‘New  
Folder’)  
@return\_val.save  
return\_data = ‘’  
render :text=\>return\_data.to\_json, :layout=\>false  
end

can anyone help to figure out the problem please!!

Thanks in advance!!
