I upgraded to NW 7.3 from NW 7.2.
I started migrating the Java Web Dynpro DCs + Projects.
The problem - I am able to build + deploy the DC but when I open the Java Web Dynpro files - I get the error message:
"This file is derived. Do you really want to edit it?".
And now every change in the file isn't saved. I can't updated the files.
Mayby Someone knows ???
