[Firebird-net-provider] bug in designtime support - it is not usable

[Liviu U. <liv...@gm...>]

I installed both net provider 1.6 and the 1.7 beta. When I put an fbAdapter
on a form at designtime I get the exception: "This cast is invalid!" ( after
I have properly configured a fbConnection ).
This error makes the whole design time support inexistent.
Is this a bug or I am the only one experiencing these problems?
