1398106 - 'Remove From History' (and other items) in the 'Downloads' context menu do not get the right state/enabled updates

Status: VERIFIED FIXED

(Firefox :: Toolbars and Customization, defect, P1)

Description

[atlanto]

STR:
0. Download something
1. Open menu panel, go to Library -> Downloads
2. Right-click on the downloaded item

Expected:
'Remove From History' indicates enabled and it works normally.

Actual:
'Remove From History' indicates disabled. It is working when clicked(selected item has been removed), but context menu doesn't disappear.

This does not occur if 'Downloads' come from toolbar button 'Library'.

Comment 1

[:Gijs (he/him)]

On OS X, the item is just always disabled for me (but somehow has a hover state, in what I suspect is an unrelated graphics/styling issue).

It seems to me that there's no code to update the state of the commands of this context menu, and any state it has is purely accidental from whatever it was before. Because opening the panel updates the delete command because of the edit UI (on non-OSX) this creates a different behaviour here, but really the core issue is that the subview should be updating the commands based on its state, and my attempts to do that so far have not succeeded. There are so many "update a command" or "update all the commands" methods and helper functions in the downloads code that it's not clear to me how the subview is supposed to do this.  Paolo, how is this supposed to work?

I think the easiest fix here is to change the static updateContextMenu method to go through the items and set them as enabled or disabled based on the result of the button._shell.isCommandEnabled method. Other views use controllers instead, and update the commands in advance using goUpdateDownloadCommands when the item is selected.

In the future we could remove a lot of complexity by avoiding command dispatchers, <command> elements and calls to goDoCommand in all views, for everything except the standard delete command.

We'll need to fix the keyboard navigation in context menus to not rely on a controller present before then. Or do use a controller, but make it a light-weight proxy that links to the view implementation.

Attachment: Bug 1398106 - Check the disabled state for each menuitem in the context menu for a Download in the Library subview.

The 'cmd_delete' command was clashing with another controller which keeps
disabling the menuitem, so it's been renamed to 'downloadsCmd_delete' instead.

nit: command implementations don't return values.

Also, you can improve the comment by saying the reason for the alias, which you already mentioned in the commit message.
