FileAction is an abstract action that operates on the currently active FileTable. It is enabled only when the table condition as tested by getFileTableCondition() method is satisfied.

Those tests are performed when:

• the selected file on the currently active FileTable has changed
• the marked files on the currently active FileTable has changed
• the currently active FileTable has changed
