You cant work any more in design view.
What is a bug? especialy in a framework that is used to develop applications? Is it only something that is described diferently in manual? I will be writing more about that in this blog by presenting the functionality of the framework i am working on. Jdeveloper 11 and fusion applications
So it had to do with security.
I enabled security in demo application and i have the same error again when i try to preview any graph from the wisard.
Is this a bug?
