| Custom Contectmenu with toolbar [message #857108] |

Hi,
I try to create a custom contextmenu in a treeviewer with opens on selection change. I based this menue on a tooltip which is not gaining focus on open.
On top of this Tooltip I added a toolbar with a ToolbarManager.
To add the Actions to the toolbar I used the MenuService:
IMenuService menuService = (IMenuService) PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getService(IMenuService.class);
toolbar = new ToolBar(composite, SWT.FLAT);
toolBarManager = new ToolBarManager(toolbar);
menuService.populateContributionManager(toolBarManager, "smart:"
+ menuId);
toolBarManager.update(true);
So on opening the custom menu all attached commands are shown with the correct enable state.
But as soon I try to click one toolbar button all commands get grayed out and get disabled.
Which part of the command framework is updating my commands. What I saw is that the Shell of the tooltip is gaining the focus. Could that be my problem?
What shall I do to not loosing my enabled state?
What I can also see is that the EvaluationContext changes. Can I avoid that?
