Hi,

I meet some problem in GUI design. I am using JBuilderX. When I switch
from source to design, it always pops up error message " Cannot set
"layout" property for this -- java.lang.illegalArgumentException:
object is not an instance of declaring class. I don't know if it will
have effect on my program.

Could anyone give me some idea why this error happening? Thanks in
advance

Raine
