问题 When I start my application it opens a JFrame (the main window) and a JFilechooser to select an input directory, which is then scanned. The scan method itself creates a new JFrame which contains a JButton and a JProgressBar and starts a new Thread which scans the selected Directory. Up until this point everything works fine.

Here is a realistic but simplified version: In parent.ts, html I have: <div class="col-md-3"> <label>Source</label> <app

This is how all my 73 components

Entities are actually just integer ID numbers, and components are attached to them by mapping the component to the specified ID number of the entity. Now, I need to store collections of entities and the associated components to a file that can be modified later on, so basically I need a saving and loading functionality.
