Handlers enabledWhen based on String in View [message #663689]

Hi,

I have defined all my commands in the ui.commands extension and i want to retrieve all the commands programmatically. I know there is something like the commandManager.getAllCommands(), but this doesn't return anything.

I need all this because I want to enable/disable all listed commands in a category at the same time...

Hope someone can help me out.

Okay, I think i'm going in the wrong direction here. I guess what I should do is add an enabledWhen for my Handlers where I check the last executed command. I can set the id of this command in my view. Is it possible or should it be done in another way?

My situation:

I have one perspective with a toolbar with a couple of commands. When executing a command, a filter is set on a tree of a view. I want to user to see which filter is set by changing the images. So one image is pressed and the rest is normal....

ICommandService (retrieved from the appropriate service locator) will
provide the list of commands for you.

I'll just point out that each command's enabled/disable state is
controlled by its active handler ... not by the command itself.
