Where or where has my intellisense gone?

I'm working on a flex 3 app using the latest flexbuilder 3 beta, both the plugin and standalone versions. For some reason, in some mxml files my intellisense just seems to not work at all. While in other mxml files the intellisense works fine. Turns out that in this latest beta release, Flexbuilder gets cranky if you use double quotations in Metadata Event tags:

[Event("forward", type="mx.events.Event")] will kill your intellisense and your control clicks. You will feel very lonely.

[Event('forward', type='mx.events.Event')] will make everything right again, blue coding skies ahead.

On a side note, the single quote is actually only necessary on the type attribute, intellisense seems to work fine if you use double quotes on the Event name itself.

Hopefully this will be fixed in the next release.
