Well I'm experimenting with Eclipse4 RCP application and have noticed I must use @Inject if I want my part would initialized. If I put only @PostConstruct my part it's not initialized. What is needed to use only @PostConstruct and get method injected?

So this works for me

@Inject
public void createPart(Composite parent) {
...
}

while this don't work

@PostConstruct
public void createPart(Composite parent) {
...
}

Over 4000 views of this post and nobody has comment. Very strange.

Why in tutorials over Internet simple @PostConstruct works and won't for me. What I'm missing?

I find it strange to complain why you're not getting a response within 10 hours on a Saturday. However it's as simple as looking at the wiki http://wiki.eclipse.org/Eclipse4/RCP/FAQ#Why_isn.27t_my_.40Inject-able.2F.40PostConstruct_methods_being_injected.3F and more details https://bugs.eclipse.org/bugs/show_bug.cgi?id=403814

Well FAQ helped. Imported javax.annotation and javax.inject packages and now it works. I knew there is a trick even it is a bug.

No you have to import javax.annotation to make @PostConstruct work!

@Miroslav,

Don't you get any compilation/launching errors when you haven't got the javax.annoation imported? Could you have checked the 'Always launch without asking' box on the Error notification pop up?
