Crepes are for weekends



Weve discussed something with
another customer recently along the same lines, Ive put out a feeler to
see if we solved their issue successfully. In theory I would say that you
should be able to solve the problem without resorting to the server (which if
you have a lot of clients hitting concurrently with different data coming back
will be put under a heavier load because it wont be able to
cache). 



Deferred instantiation is probably not
taking hold in your case because youre explicitly calling createChild
(Im guessing). If you created object descriptors and then
instantiated the children using them you could probably do a queued policy that
would speed up the responsiveness. The creation of those object
descriptors of course is a little more dicey since I dont think we
document them all that much.



Ive pinged Alex, lets see if
he comes up with anything

Key point here is the server deals with the processor hit, not the
client.

Secondly, the Flex server has caching built in,
and won't compile the XML 
everytime, even if it changes often.

That way for each different XML, backend Flex
server needs to compile
it into a new swf, which, in my experience, has
been a not so fast
process. Robert's screen is going to hang either
way.

But frankly, I don't have a solution :(

 So my flex app gets this XML chunk, I loop
through the XML and based
on certain parameters in the example XML above,
and in each loop, I
call createChild on a Form component I have in my
MXML file and I
build a form that displays to the user various
filters they can set
for the report they just selected.



 I'm dynamically generating DateFields,
Textfields, Lists, and a
custom Range component that I created whose MXML
file looks like this:



 ?xml version=1.0
