From Csabi:

I have a MenuListener which reconstructs it's submenus in #menuSelected. The problem is that menuItemWithPath tries to find the last menu item from the path given to it without gradually activating previous menu items.

I think that menuItemWithPath should activate each menu item from the path given to it, one after the other, just like a human user would do.

The situation is similar in the case of trees. Nodes could be added upon expansion of a parent node, for example. I haven't checked if FEST currently takes into account this possibility, but I think it doesn't. Whenever paths are involved JTreeFixture should proceed as follows: it should gradually make the path visible, for example, given the path (A, B, C, D) it should make visible the paths (A), then (A, B), then (A, B, C), and finally the entire path, (A, B, C, D).

Thanks,

Csabi

まず menuItemWithPath と JTreeFixture のパス処理のエントリーポイントを追跡し、次に MenuListener#menuSelected が遅延作成されたサブメニューをどのように公開するかを調べます。メニューパスが段階的にアクティブ化され、遅延作成された JMenus とツリーノードが各ステップで利用可能になること（(A, B, C, D) のようなパスを含む）が変更完了の条件です。
