[Seaside] Smalltalk question

[Dmitry Dorofeev]

Hi all.

I'd like to create an instance of class by knowing only a class name.

something like this:

classname := anObject class asString , 'Controller'.
"expect something like FSBlockListController in a classname"

controller := Smalltalk giveMeInstanceOf: classname.
"expect result of /FSBlockListController new/ in controller"

I know it should be possible in Squeak in one line of code, 
but i am still a newbie...

Thank you very much.

-Dmitry.
