[flexcoders] Re: Trees, DataProviders and dynamic screen updates

2008-07-24 Thread Eric Cooper 
Thanks, Tracy.

What I meant was that I was adding Objects like { object:myObject } to 
ArrayCollection - 
where myObject was an instance of a proxy class - and whose properties were 
getting 
changed. 

I have now gone to a slightly different scheme, adding Objects like { 
object:mpObject, 
value:myObject.value } - and when 'value' property changes, I iterate through 
ArrayCollection, looking for match on 'object' - and, when I find that, I set 
'value' to new 
myObject.value. This seems to trigger necessary dispatch and Tree's rendering 
updates.

Thanks again for your help.

 Is there a way to touch the ArrayCollection so as to prompt Tree to

  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!

That sounds like unnecessary work.

 

Again, when you say and whose properties were getting changed, how are
they getting changed?  By simple assignment?

 

If so, then you can call the ArrayCollection.itemUpdated() method.
