I like it when Java throws an exception at line 53 in a class having 42 lines of code :)

Hi @Siedlerchr! I'm interested in fixing the redo and undo buttons being active without an open library.

Plan:
Investigate how the button state is managed.
Implement logic to enable buttons only when a library is open.
Test thoroughly to ensure correct behavior.
Update documentation as needed.
I'll start looking into this and reach out if I have questions. Thanks!

I think @melisomez is already on it at #11839

It's related but not the same. we need to integrate an additional check e.g.
this.executable.bind(needsDatabase(stateManager)

Hey @faresbouzayen, are you actively working on this? I see that you have not even forked the repository yet. Do you need any help? If busy, you can pass this on to other students.

Yes you can assign to someone else

@maintainers shift this to free-to-take.

Hi @Siedlerchr
I'm part of a group of five students looking to contribute to this project as part of an assignment.

Our plan for this issue:

• Understand how the Undo/Redo buttons enabled/disabled state is managed, specifically what causes the state to change.
• Investigate the use of "libraryTab" referring to the posted stacktrace.
• Implement logic between button state and library's open/closed state.
• Write tests and documentation.
• Submit a PR if we appear to have solved the issue.

We plan to focus on this for the next 1-2 weeks if assigned. We will engage through the comments, and state if we cannot solve this issue so that it is available to others promptly. Thanks!

I was going to assign @melisolmez as her comment expressing interest (#11839 (comment)) is older, but final call on you guys as it's a university assignment for @damgam0288.
Alternatively: You guys can also suggest any other good first issue to them, if that works.

As this is a oneliner it does not make senes to address it with a lot of people so chose any other issue
