Matt And Manish

Hi Manish and Matt
 
Its not simple as you describe . even the documentation does have a bug , i've tried the code from below and the output is
[object],[object].....
 
 
let me remind you that my objects are jave objects that come from the server in SOAP and i have no idea what flex does with them , and believe me i tried and read all your documentation .
 
Manish your example is good for Tree that was built on XML and not from objects , cause in my case you would have
get [object Object],1,[object Object]
 
my Java objects are very simple they like this
 
class SystemFile {
   
    String fileName ;
    String fileGuid ;
}
 
class SystemFolder{
   
    String folderName;
    SystemFolder[] childFolders;
    SystemFile[] systemFiles;
}
 
trying to get to item.folderName didn't work also not item.fileName.
 
i didn't find any way to access my original object members besides backing object , what is wrong here ?
 
thanks Shlomi

Also check out the TreeDataProvider API.  You should always use the methods specified in that API when working with either XML or Objects in a Tree or Menu.  That way you don't have to worry about backingObject which is an implementation detail purposely not documented.

If you're writing a labelFunction for a tree, you're expected to know
the format of the item so you can construct the label string out of
the data within the item.  For example, I have an item with properties
'name' and 'phone' (number), and I want the label to be a combination
of both:

  <mx:Tree labelFunction="makeLabel" />

   function makeLabel(item):String
   {
      return item.name + ": " + item.phone;
   }

makeLabel() is called for every node in the tree.
