RE: [flexcoders] Using the XMLListCollection class bug

Fri, 30 Jun 2006 07:46:45 -0700

The situation you describe occurs when the xml nodes are the same i.e.
 
<root>
<items>
<item label ="1"/>
<item label ="1"/>
<item label ="1"/>
</items>
</root>
 
There needs to be a difference between the items in order for flex to react properly.
 
so the below would work
 
<root>
<items>
<item label ="1"/>
<item label ="2"/>
<item label ="3"/>
</items>
</root>
 
notice the @label here
 
<mx:tree labelField="@label" />
 
hope this clears things up, if your still having problems after this then post back an example to show what it is doing.
 
Just remember nodes have to be unique, and it works like a charm. I ensure this with a guid.

Thank you, Jason,
this is a great news!

As I said, maybe it is a bad example, or maybe I just don't know how to use it?
Because when I add some "bananas" to the list, first they are not selectable except the last one,
then when they are removed, they are not properly removed from the tree, and on the end the tree can't render anymore.
I'm interesting in this because I'd like to write a "lazy tree", to get child items from database when they are needed (when the node is opened).
If anybody has done this and could give me a hint, I'd be gratefull.

Thanks, Milan

I'm very happy to report that the tree component is working very well. All the outstanding bugs I've checked have been corrected (i have a few left to look into). The binding is working.

Hi,
I'd like to report that example in chapter "Using the
XMLListCollection class"
(http://livedocs.macromedia.com/flex/2/docs/00000513.html#406668 )
which can be found under (Flex 2 Developer's Guide > Building User
Interfaces for Flex Applications > Using Data Providers and
Collections > Using hierarchical data providers) does not work as
expected and produces very strange results.
Could somebody confirm that f2b3 bug in tree dataproviders is removed
or not? Maybe there is problem only with example.
I'd really like to know if Flex 2 allow to make dynamic databinding
for Tree component. Any hint or working example would be highly
appreciated.
Milan
