Class diagrams are great. RAD 7 has them and it generates and updates code based on them. Lovely.
The forward and reverse engineering capabilities, the works.
Now if you refactor the classes and change package names… then you’re in trouble. The class diagram is like, oblivious to the change and being unable to find the classes the diagram is based on it just chokes. So just be aware of this possible problem.
How to fix this:
- Open the dnx class file with RAD’s XML editor.
- Search for the term “srcfolder” – this is where the diagram looks for your source code
- Do a replace all for the value srcfolder is set to – e.g. srcfolder=src%5B (the %5B stands for the URL encoded ‘]’ character – and set the replacement value to the new refactored package name – e.g. srcfolder=src/java%5B
Now open the diagram again using the DNX file viewer and voila – your diagram is back!
