jAfter upgrading from 5.5 to 6.0 all my Matisse forms open OK except one
that gives null pointer exception when trying to open it.
How can I try to fix it ?

Hope the form is not corrupt. Can you mail the form to me. Ill try opening it at my end.

[paulmol]

I resolved it.

It was missing some sub-components from custom palette
which got lost in the process of upgrading 5.5 -> 6.0

Error messages could be more specific.

Btw I still don’t know how to preserve custom palette components
while upgrading MyEclipse other than taking a good list before upgrade and adding them again.

For each component you need to pay attention if it is a “widget” or a “form”.
