Is there at least anything other than Vogella's tutorials and his book, which is completely based on those tuts? Examples from his repo are often either incomplete/unfinished/won't run and those examples even don't match the book actually..
I'd like to find at least some javadoc for this, because any step to a side and I'm completely lost on how to accomplish different tasks and what functionality is available.
After almost 2 years there has been no decent response to this question. So i'm considering the Eclipse E4 platform efectively dead, as there are still people voting for this question and can't find an answer.
The only answer I have is - move to the NetBeans Platform. There are similar problems there, but at least people do answer in the mailing list and there are books which are quite more recent and are actually providing working source code! Enve the NetBeans website provides free tutorial on a lot of stuff for free!
I mean it's really hard to believe, but you should try NetBeans platform - it's the only choice.
