How to manage key conflict handler of different commands in multipage editor - eclipse

Question

I have multipage editor and i'm using different commands in two pages with same key sequence 'M3+O'. I am getting key conflicting handlers.
Error:
!MESSAGE A conflict occurred for ALT+O:

</context>
</extension>
Activation and deactivation: It is done through activation and deactivation of context. Below is the code snippet on page change.
Activation in 1st Page:
private void activateHandlers() {
IContextService contextService = (IContextService) (PlatformUI.getWorkbench().getService(IContextService.class));
if (contextService != null) {
activation = contextService.activateContext(IControllerConstants.CONTEXT_TAB_ECLIPSE_CONTEXT_ID);
}
IEditorSite site = getEditor().getEditorSite();
IHandlerService service = (IHandlerService) site.getService(IHandlerService.class);
IHandlerActivation nodeActivation = service.activateHandler(AddNodeHandler.COMMAND_ID, new AddNodeHandler());
activatedHandlers = new ArrayList<IHandlerActivation>();
activatedHandlers.add(nodeActivation );
}
Activation in 2nd Page:
private void activateHandlers() {
IContextService contextService = (IContextService) (PlatformUI.getWorkbench().getService(IContextService.class));
if (contextService != null) {
activation = contextService.activateContext(IControllerConstants.CONTEXT_TAB_ECLIPSE_CONTEXT_ID);
}
IEditorSite site = getEditor().getEditorSite();
IHandlerService service = (IHandlerService) site.getService(IHandlerService.class);
IHandlerActivation methodActivation = service.activateHandler(AddMethodHandler.COMMAND_ID, new AddMethodHandler());
activatedHandlers = new ArrayList<IHandlerActivation>();
activatedHandlers.add(methodActivation );
}
Deactivation similar in respective page:
public void deactivateHandlers() {
IContextService contextService = (IContextService) (PlatformUI.getWorkbench().getService(IContextService.class));
contextService.deactivateContext(activation);
IHandlerService service = (IHandlerService) getEditor().getEditorSite().getService(IHandlerService.class);
if (activatedHandlers != null) {
service.deactivateHandlers(activatedHandlers);
activatedHandlers = null;
}
}
Even after deactivation / activation on page change, the conflict appears.
Please let me know if there is a better approach.
Thanks.

Use a different context id for each page. You could make your main com.sap.adt.wda.controller.ui.contextScope the parent of each page context.
