Hello together,
i am developing an eclipse rcp application and would like to use the EMFCP plugins. i started with this tutorial: eclipsesource.com/blogs/tutorials/getting-started-with-the-emf-client-platform/
after plugin installation, my eclipse opens a default workspace every time i start it and i am not able to change it back to save the last known workspace. at least the "switch workspace" option works fine.
In addition: after 1 or 2 starts eclipse takes more then 10 minuts to load the workspace.
i tryed to install the EMFCP plugins into a new eclipse with same results.
also: where is the bugtracker for the project? the link from the homepage (http://www.eclipse.org/emfclient/support.html) is a dead end.
any one else with this problem?
thanks
PS: I am using eclipse kepler and also tryed it with 4.2

Hi,
I can reproduce this. I have created a bug for this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=416531
It has probably something to do with the initialization oder of
services, however hard to debug. I will try to fix this a soon as
possible. In the meantime, I hope this is no blocker for you. If you
want to avoid manually switching your workspace everytime you re-start,
you might want to define an explicit target platform and add ECP in
that. That allows you do deinstall it from the IDE as long as the issue
occurs.
Regards
Jonas

Hi,
the issue should be fixed in 1.1.M1, I suggest you upgrade to this version.
http://eclipse.org/emfclient/download.html#milestone
Please tell me, if this resolves the problems.
Regards
Jonas

Hi,
looking at the line where the NPE is thrown let me assume, that the
model element is null (getModelElement()). Could you please check this?
getModelElement() should return the EObject to be opened.
However, in 1.1.M1, we provide a new API, which makes it much easier to
create an editor. We are planning to deprecate the ECPControlContext in
future versions. However, the new API does not yet support references
features yet. If your EObjects only have simple attributes, you can
already try it. It is documented here:
http://eclipsesource.com/blogs/tutorials/emf-client-platform-how-to-customize-the-editor-layout/
(last paragraph)
If you experience any more issues, you can also contact me on Skype if
you want: "JonasHelming"
Thanks for the feedback!
Regards
Jonas
