what had happen to this?

[mathidioticz]

What does the error "A previous error prevented bean from being created" mean?
I am trying to open up a Swing window in Visual Editor but could not see all the widgets. I can only see a "this" icon, with "i" indicator which is shown as the image below.
I do not know how to solve this error..
Please help me.
