Hi all,
I've an RCP application which should check some points at startup.
Therefore, I created a LifecycleManager and added a method public void
checkOnStartup() (annotated with @PostContextCreate). Now I have to
check if some preferences are set. But somehow I can't get the
IEclipsePreferences object from context. The checkOnStartup() method
gets an IEclipseContext injected, but this didn't help me.
Additionally, I want to start a command with ECommandService. But this
service isn't available, too. If I try to inject these services into my
LifecycleManager the methods were not called, anyway (this looked very
strange to me... no error message appeared!).
How can I access these services in LifecycleManager?
Thanks in advance,
Ralf.

Hi Dirk,
Thanks for your answer. I think I will omit the using of these services.
The only reason why I wanted to use them was that I thought it would be
easier to launch a dialog via a Command. I have to check some things
before the application is launched. Now, I will implement it as a simple
dialog, which is easier at this point.
For the Preferences I'll use the OSGi Preferences Service, which is
available at this point. Im a little confused about the different
preferences (one from Eclipse and one from OSGi context).
Regards,
Ralf.
