I have two features in SharePoint 2010 project. Every feature has its own button that have to be placed in different groups on the same custom tab.
Feature1 adds "Hello" group with "Say Hello" button to tab "My Custom Tab"
Feature2 adds "Bye" group with "Say Good Bye" button to tab "My Custom Tab"
I've tried to create empty tab and to use its Groups id for location attribute in CommandUIDefinition for group like this:
with no luck.
