RE: [flexcoders] How to populate tree control from web service re sult (server side java objects)

Tue, 19 Apr 2005 10:37:45 -0700

Hi Guys
 
Thanks , but i already saw this one , and frankly its not enough , its only talks about primitive types and say that if you have complex object you need to write AS code for it (which will be discovered automatically).
 
Now this one is important - There is a property of a node item that is called "backingObject"
macromedia don't have any documentation on it (Why ??) i found it using  the debugger.
this object holds all the members of the complex objects , so you can refere them as something like this
 
node.backingObject.java_member_name
 
Have fun with it

Hi
 
The label in the tree shows fine , but trying to use the labelFunction was a little bit confusing.
how ActionScript map my Java objects to AS objects , ? can someone send a GOOD article about this?
 
if i have a function that get a node like this
 
   function myLabelFunc(item):String {
      
        var type=typeof item; // always return {Object}
        return item._???????
       }
how do i know which properties the variable 'item' has ?
 
thanks
 
Shlomi

The top-level object in your tree can be assigned directly to the
Tree's dataProvider property.  If every object has a "label" property,
then that'll be used to the label; otherwise you can specify
a labelField to use another field, or a labelFunction to format the
data the way you want it displayed.  Look out for these properties in
the Tree documentation.
