Hi everyone,

I found about the capabilities of Flex/Air a few weeks ago and I started experimenting. I'm interested in the mobile apps in particular.

I downloaded the final release of Flash Builder and started to "code" a few things (I am fairly new to ActionScript too).

The thing is I have errors when launching the mobile apps on an emulator or on my Desire HD.

Typical example is this app from Ryan Stewart : http://blog.digitalbackcountry.com/2011/03/slides-and-assets-from-adob e-refresh/

I tried to run his CollaborationMobile App (as I want to work with LCCS) onto a device emulator thanks to Flash Builder but I get the following errors :

VerifyError: Error #1014: Class mx.containers::Canvas could not be found.

and a few others...

I have no clue of the reason of these errors...

Thanks for the help
