Yes I am doing that, if I run the Dialog standalone I get the desired result, but when it's being created and invoked from my application it retains the decorations. It's like it's in inheriting the properties from the parent JInternalFrame.

in the absence of any code, all I can guess is that you have a duplicate declaration of the dialog,
when invoked from the internalFrame i.e. the undecorated one is not the one showing
