Thanks Yves,
I think that will work :)
The reason I want to do this is because I'm working on a component to allow
multiple filters to be easily assigned to a DataGrid
(http://tech.groups.yahoo.com/group/flexcoders/message/143771), and to also be
able to work with multi-dimensional
Could someone please explain to me how closures work in ActionScript? I
am attempting to create a set of Flex Form fields, and assign an
event-handler to each of them, however, it seems that after creation,
all of the fields have the same event handler.
For example:
var i:int = 0;

Thanks for all of the help guys! I have gotten things pretty much
working now: I just need to sort out some issues relating to working
with multidimensional data-sources, which I'm going to post in another
thread. In case it is helpful to anyone else though, here is the
near-completed class:
Does anyone know a method to dynamically index an arbitrarily deep array
or object-literal?
e.g. Given an object t, and the string one.two, how can you access
t.one.two?
Here is some sample code to demonstrate the problem:

I'm testing the variable during the FilterManager constructor. I
actually don't have Flex Builder, so I've been using Alert and
ObjectUtil to output information about the variables at run-time, e.g.:
public function FilterManager():void {
super();
Hi Valdhor,
Thanks for the suggestion, that is a very good idea and something I hadn't
thought of. I'll certainly try that out, however, I'm still uncertain as to how
to pass in / accept data in custom AS classes. For instance, when I specify
things as MXML parameters, are they available in
Hi Steve,
Thanks, that makes things pretty clear. I'm still having trouble passing in
variables. For example, in the MXML example above I specify a test variable.
When I try to access it in the FilterManager constructor, however, the variable
is empty (both test, and _test).
I must be missing

Hi all,
I have been working on my first custom ActionScript component and have
been trouble getting the data-binding setup properly.
I am trying to making a FilterManager component which will enable to
the user to filter based on one or multiple columns in a DataGrid. In
order to do this though
if (myPanel != null)
myPanel.title = TEST;
That did the trick!
So it looks like the resize event *is* being fired as soon as the application
is being loaded, before the panels have even been instantiated?
Thanks for the help
Hi all,
I am getting run-time errors in strange situations and was wondering if
anyone might be able to provide some insight as to what is going on.
If I try to attach a resize event handler to the Application class,
and refer to other components within the application, I end up getting
run-time
var a:Number = obj1.number;
var b:Number = obj2.number;
That made things much more clear.
The reason things weren't working for me was because I expected the sort
function to receive only the variable mapped to the column (i.e.
number) and not the entire row. The
Hi all,
I have a problem related to sorting type-casted numeric data, and was
wondering if someone could help me out:
Given some numeric data stored as strings (11.5), how can I populate
it into a DataGrid and have it sort properly?

Nope. Just responding to screen resizes. The application is set up to

You can use an expression in binding braces. Try this, see if it

The reason is that I have some
