Re: [flexcoders] Re: Enable / Disable Flex Menu Items Programmatically using AS 3.0
Hi, Without looking at your exact dataProvider with a simple Application, I can't help much. I got this to work yesterday using @enabled = false on the node. But the ex4 implementation various on 'WHERE' you are trying to set the enabled of the node. Can you post a simple mxml Application?

RE: [flexcoders] Re: Enable / Disable Flex Menu Items Programmatically using AS 3.0
Is this the thread where you are not able to use the normal method of doing this via the dataProvider, but must have some way to do it via the instantiated elements? Because you are trying to automate unit testing or something? Because programatically disabling a particular menu item is easy. Just get a reference to the menu item node and set the enabled attribute. Is that not acceptable to you?

Hi stranger bc24fl, Mike Schmalle had proposed you the exact solution, that we are currently using within our project based on Flex 2 SDK to enable/ disable menu items in MenuBar component. I do not understand without looking at your code, what is going on wrong with your MenuBar. Can you post a dummy sample of the code online to illustrate your problem? SWF with View source option enabled would be nice. ps Why do you post anonymously to this list, BTW? I would like to reference you by your name ;) -- -- Med venlig hilsen / Best regards Andriy Panas [EMAIL PROTECTED] On 03/06/2008, bc24fl [EMAIL PROTECTED] wrote: I'm really struggling for help.

RE: [flexcoders] Re: Enable / Disable Flex Menu Items Programmatically using AS 3.0
Yes, it can.
Valdhor's example works for me. There is something going on with the
programmatic instantiation of the menu, it dissapears on click unless it
gets recreated in the handler. That is just a bug and not necessary to
demonstrate the technique of disabling a menu item.

Ok I think I'm getting closer. In your example you create the menu
when the user clicks but in my code the menu has already been created
