This is not easy to fix; plugin assemblies need to be loaded for the options interface to enable/disable them, but the plug-in invocation mechanism bypasses the plugin assembly registration structure.

Ok, lovely... when trying to solve bug #748 (http://sources.ecopath.org/trac/Ecopath/ticket/748), plugin assembly enable/disable dynamics were removed which stopped the UI from dynamically responding to plug-in assembly changes. However, this 'fix' introduced this very bug:

The UI plugin handlers were relying on a plugin to get disabled AFTER loading in order for menu items to disappear from the UI!

The plugin enabled/disabled system has the fundamental flaw that loaded plug-ins are immediately integrated in the UI before the plug-in manager is told to disable specific plug-ins. This can only be fixed by letting the plug-in manager maintain the enabled/disabled settings which will be assessed during plug-in loading.

  • Status changed from new to closed
  • Resolution set to fixed

Fixed the fundamental flaw; the plug-in manager assess at startup which plug-ins are allowed to work, and only those plug-ins are loaded and can be queried for plug-in points. If a plug-in stops working the plug-in manager can decide to shut the plug-in down.
