Programmatically update all tooltips when context changes? [message #1792722]

I'm using the compatiblity layer under e4.

When switching contexts, the keybindings in tooltips of commands are not updated.

For example:
Two different editors with the same command are side-by-side.
The command has two keybindings for different contexts.
A part listener switches context when the editor is activated.

Although the keybindings are changed correctly, they are not displayed in the tooltips of the command.

MLocalizable#updateLocalization only updates the localization but not the keybinding.

HandledContributionItem#updateMenuItem seems to update a tooltip with the keybinding,
but I have no idea how to obtain all these items using the ModelService#findElements to call this method.

Could you please hint me at what to update when switching the context?

Normally, there is no need to sync the context manually on part change.
Did you try EContextService#activateContext(contextId) when creating the part?
In E4 with compat layer you would use org.eclipse.ui.contexts.IContextService.activateContext(String)

As written before, the keybindings are working correctly. This is how the context is switched:

final IContextService contextService = PlatformUI.getWorkbench().getService(IContextService.class);
contextService.activateContext(contextId);

The problem is that the keybindings in the tooltip are not updated. It shows the old keybinding although the new one is active already.
I want to trigger the update of all tooltips programmatically. How can this be achieved?

In your part's init() method you should be using:

cs = site.getService(IContextService.class);
cs.activateContext(...);

This will return the part's context service instead of the global workbench window context service.
