Share Model Editing example [message #589677]

I am not able to use Share model editing example.

This is how I tried:

I am running a local server by using startserver.cmd.

First user:

I created a simple project and connected to server by ECF menu for that
project.

I created Data Graph model and opened an ecore file.

Second user:

I ran another instance of eclipse by using another workspace.

Created a new simple project, connected to same local server by using ECF
menu.

Created data graph model and linked (Advance -> link to file in file system)
it with the same file in first workspace and opened same ecore file.

Now, any change I make & save, is not reflected automatically to another
user.

I am not sure what I am doing wrong, any thoughts?

More or less, same is true for ECF Graph Share example. But it also
throws null pointer exception if one user makes the changes and another
user closes and opens its diagram.

Hi Folks,

I think there is a newly introduced bug in the graphshare example
application. I will take a look at it tonight (Fri) and this weekend.
I don't suspect it will be difficult to fix once I reaquaint with that code.

We (ECF) are anticipating doing an 0.5.2 build within the next couple of
days (certainly before next Thurs). I will try to make sure the fix for
this issue gets into 0.5.2. I would appreciate it, though, if someone
(Parvez?) could submit this as a bug report via bugs.eclipse.org...to
the ECF bug area?

Thanks!

Scott

So it seems that this problem is the side effect of a different bug that
prevented the state of the graphshare editor from being saved properly.

I believe I've fixed this other bug and the fix will be in release 0.5.2
which we will produce in the next few days.

Thanks again for the report.

Scott
