Hello. I wrote a program and loaded a lot of data : dir,files,serialized frame etc.

I used it and found updates to add so I changed the class so to speak by making the changes. Now of course the
same serialized frame will not open so I can not access the data with out reloading it. I expected to have to
reload all the data however, I would like to know if there is a way to manipulate the class ID or Whatever has changed
so the serialized frame in a JDesktop will re- open the JInternal frame? The frame is just a picture really that access the dirs' so that should be the same but stuff in the abstract action or some other piece of code was changed
but the JInternal frame (picture) has not changed.
