SwingObjectWidget: set values by string comparison #87
Conversation
Previously, we were trying to set the JComboBox value with a new instance of the object. We don't always have the possibility to keep a list of the allowed choices for the current model, nor can we override the `equals()` method for the `Object`s of this widget instance. So we have to fall back to comparing all combobox items to the current value by their `toString()` and `ObjectService.getName()` strings.

This is awesome. The reason I didn't merge it instantly is because switching to string comparison over reference and/or object equality is a fundamental change in how the widgets behave, and it honestly makes me nervous that there will be unintended consequences. E.g. it's possible to have two different So... testing needed. I hope to get to it extremely soon; I know how annoying this bug has been. |
