[flexcoders] Re: Example of Object.isPrototypeOf ()
What exactly does it mean when the Flex doco says: This method returns true if the object is in the prototype chain of the object specified by the the Class parameter. What does prototype chain mean here? Sorry for my ignorance if this is a dumb question. And are you saying this is an obsolete method? --- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: Flex makes almost no use of AS3's old-style prototype-based inheritance; it uses the new class-based inheritance.

[flexcoders] FlexBuilder Project Layout Help
Where does FB keep information about your workspaces? The reason I am wondering is because I have deleted my FB workspace from the file system but when I try to recreate it in FB, FB tells me the work space would overlap. It still thinks the old workspace is around. Maybe someone could tell me where to look to fix this : ) Thanks, Ros
[flexcoders] Re: FlexBuilder Project Layout Help
that was what I originally did and FB still thinks it is there.

[flexcoders] Data Binding (I think) question
Using Flex 2 - I have extended ComboBox in an AS3 class. My plan is to use it a lot in several places and just programatically change the dataProvider in each of the places. It works as expected the first time I use it in a generated screen. Later I remove the screen, then still later I recreate the screen containing the combobox. This time the dataProvider still gets updated, but now no data is visible in the dropdown on the screen - it appears empty. I figure it needs to be rebound to the screen somehow, since I have verified I have data. However, I cannot figure out how to bind the instance of the combobox, and / or exactly what else in it besides the dataProvider, in such a way that the screen gets updated. Could someone give me some pointers, or at least some idea of what I am doing wrong? Thanks, Roscoe
[flexcoders] Re: Data Binding (I think) question
OK, what you put is exactly what I am doing, almost word for word.
When i set my dataprovider to a new ArrayCollection - the first time
it works fine, then after that it works but the new data does not
appear in the combobox. All the bindings appear to fire, and the new
data is in the backing ArrayCollection as seen from the debugger.
However, on the screen the dropdown is now empty. Hence my thought
that I somehow need to create or renew a binding between the combobox
and the .mxml file (the screen) that it is nested in.
I appreciate your help.

So if i got it right, you want a custom ComboBox on several screens
and the only thing that is going to change is the dataProvider, right?
I would do the following:
1. In your custom ComboBox declare a variable like this:
private var _myDataProvider : Array; //or ArrayCollection, as you prefer
2. Create a getter and setter methods
[Bindable]
public function get myDataProvider() : Array
{
return _myDataProvider;
}
public function set myDataProvider(dp : Array) : void
{
_myDataProvider = dp;
this.dataProvider = myDataProvider;
}
3. In the application where you want to include the custom ComboBox,
pass the dataProvider you want to use, like this:
custom:CustomComboBox myDataProvider={DataProviderYouWantToUse}/
or
var myCustomCB : CustomComboBox
myCustomCB.myDataProvider = DataProviderYouWantToUse
Please consider that DataProviderYouWantToUse is the array (or
arrayCollection) that you want to use as dataProvider for your
ComboBox. When setting the myDataProvider, the setter will be called
and the dataProvider will be updated.
Hope this helps you out

[flexcoders] Trace(), not in debug mode? [Flex 2]
Hello, Is it possible to obtain trace output to the console or to a file when not running in debug mode?

[flexcoders] Flex 2 - Extended Tree, now events aren't working : (
I just want to make sure that this is supposed to work this way: If you extend the Tree control, it should still open and close the nodes when you click on them, unless you override the click or change functions, right? Or do you have to implement them youself? I extended the Tree control and set the dataProvider to a valid XML source. It displays the root node but will not expand when I click on it. If I manually expand them using the descriptor it works, but I don't want to rewrite Adobe's fine methods. I know I have missed something simple somewhere...if someone could give me a little nudge in the right direction.

[flexcoders] Re: Can Flex 1.5 coexist on the same machine with 2.0?
I want to install the beta, then make a copy of the production app, then compile it to see what all is gonna have to be re-written. If I install it on my local pc and or the development server containing Flex 1.5, are there any co-existance issues I need to be aware of? I am running FlexBuilder 1.5 and IBM RAD Application Developer (Websphere) on my local PC. I ~do~ need to be planning a migration to Flex 2.0, don't I?
