Bjorn, I have been looking at this (as I would like a mocking framework for Flex too) this evening and I've had no luck either.
The the registerClassAlias() does add the alias to a given class I can't then get anything to accept it as being of that type - I'm not sure what the alias is, but dumping the describeType() results shows it as an alias property on the type and not as an implementsInterface node, which is what we need. I may not have been fully understood what registerClassAlias though. But it looks (ok, it's late and I'm tired so it may just be that which is causing my negativity) as if trying to get a class to implement an interface (or at least appear to implement an interface) dynamically at run time is a futile effort. Any thoughts? -D --- In flexcoders@yahoogroups.com, Bjorn Schultheiss <[EMAIL PROTECTED]> wrote: > > try add > flash.net.registerClassAlias( "attempt.TestInterface", TestInterface ); > prior to your cast attempt. > > > regards, > > Bjorn > > > On 17/10/2007, at 1:06 PM, aduston1976 wrote: > > > lus I see a number of places on the web where the idea is mentioned, > > e.g. http://www.herrodius.com/blog/?m=200704 .
