What if you have the HTTPService result handler copy lastResult into some
other variable, and bind to that instead ?

RE: [flexcoders] data binding limitations?
Binding directly to lastResult is hard to debug. I advise using a
result handler function to set an instance variable, and bind to that.

Subject: [flexcoders] data binding limitations?
Hello everyone,
I am experiencing some very strange behavior regarding data binding.
First off, would anyone know why the following XMLListCollection does
not bind successfully to its source,
mx:XMLListCollection id=xlcUsers filterFunction=filterUser
source={xmlSetup.lastResult.USER}/
The xmlSetup is a HTTPService that returns a list of user accounts in
e4x format. The moment I add a binding tag, like the one below, the
XMLListCollection has all the data I expect.
mx:Binding destination=xlcUsers.source
source=xmlSetup.lastResult.USER /
I have several XMLListCollections bound to HTTPService results, and I
never had to create explicit bindings.
The second question is maybe related: Are there limits how many bindings
you can have in an application? It seems to me that, as the application
grows, and as I am adding more and more databound controls, previously
succesful databound controls loose their bindings silently. They can
be brought back by explicit calls to executeBindings but that sort of
defies the purpose of having it done automatically - if you have to be
explict, you may as well assign values upon change events...
Am I missing something...or does anyone else have similar experiences?
Thanks much
Iko
