[flexcoders] Trees, DataProviders and dynamic screen updates

[Eric Cooper]

Hi,
I am trying to display changes in state for proxy objects (where real state 
exists on a 
server). I have defined a Tree and set its dataProvider to be an 
ArrayCollection. I have tried 
having this be an array of references to actual proxy object and also as array 
of dynamically 
created Objects (of form {name:foo.toString(), object:foo}

Server-side events result in client being notified that properties in proxy 
object have 
changed. I would like these changes in proxy object properties to propagate 
through the 
Tree's items.

I have searched docs and this forum, but not found anything that addresses this 
issue. At the 
same time, I suspect that this is something that has been discussed - and may 
simply involve 
setting some flag on the Tree or the DataProvider...

Thanks for any help!

If you use the ArrayCollection API to make the updates to the
dataProvider, the changes should automatically reflect in the UI.

 

How are you updating the ArrayCollection items?
