No menu when launching newly built e4 application [message #997586]

hi,

I'm trying to follow this E4 tutorial: http://eclipsesource.com/blogs/2012/05/10/eclipse-4-final-sprint-part-1-the-e4-application-model/

I can generate a new E4 Application but when I launch it, a new window pops up but there is not content at all. It should contain a toolbar and two menus, but there is nothing.

I downloaded a fresh SDK-4.2.1 build and added the e4 tools from here: http://download.eclipse.org/e4/downloads/drops/R-0.12-201206131100/repository/

Does anybody have a clue what I'm missing here? Why no menus?

Try using the live model editor ('org.eclipse.e4.tools.emf.liveeditor') to browse the running model. See if your menu/tool items are there.

hi JD,

I must confess that I'm new to e4, so I might be missing something obvious here.
That said, I found a view called "Live Application Model". There is no distinction between views and editors afaik, and there is nothing else named "live ..." so that must be it (plugin-spy doesn't show useful information for this view for some reason)

Anyway, I see content in this view and the content roughly matches the IDE itself. I can see the main window and menu items like "navigate" and "project". When I start my product and the problematic empty window pops up, the Live Application Model view does not register anything new. Would you say it should now show another window representing my product?

Not sure if I follow exactly, when you launch your E4App include the org.eclipse.e4.tools.emf.liveeditor (and dependencies). Then when you application starts press ALT+SHIFT+F9 and it will display the running model. Check to see if the toolbar/menu items are listed. If not try generating a new E4 application project with the wizard.

Did you clear the persisted state (or workspace) in the second launch when you added toolbars and menus?

If so, check the error log as there should be something if it doesn't show correctly.
