That's the bug. Would you happen to know when the bug will be fixed
by the community? Would it be fixed in the next Eclipse service
release, or maybe available sooner via the dedicated EMF update
site?<br>

Yes, I'll fix it in the next service release. I'll try to get a
build in place and on the update site for SR2 in the coming weeks;
I'll add a comment in the bug when that's done. You could use the
pre-SR1 version in the meantime...<br>

Thanks Ed, <br>

Just to confirm, will the following update site
<a class="moz-txt-link-freetext" href="http://download.eclipse.org/modeling/emf/updates/releases/">http://download.eclipse.org/modeling/emf/updates/releases/</a> have the
fix as well or I would be safer to use the original indigo update
site for that? Strangely enough, the emf update site above has emf
until version 2.5...<br>

The aggregate site is probably the easiest:<br>

Thanks Ed, <br>

Just to confirm, will the following update site <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://download.eclipse.org/modeling/emf/updates/releases/">http://download.eclipse.org/modeling/emf/updates/releases/</a>
have the fix as well or I would be safer to use the original
indigo update site for that? Strangely enough, the emf update site
above has emf until version 2.5...<br>

Yes, I'll fix it in the next service release. I'll try to get
a build in place and on the update site for SR2 in the coming
weeks; I'll add a comment in the bug when that's done. You
could use the pre-SR1 version in the meantime...<br>

That's the bug. Would you happen to know when the bug will be
fixed by the community? Would it be fixed in the next Eclipse
service release, or maybe available sooner via the dedicated
EMF update site?<br>

That sounds like <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=359043">https://bugs.eclipse.org/bugs/show_bug.cgi?id=359043</a>.
:-( A bad regression.<br>

Hi, <br>
<br>
I have a very strange bug in EMF with Eclipse 3.7.1 which
was not before in version 3.6. <br>
<br>
When I try to do a move of one node in my EMF based
editor, I get a null pointer exception.<br>
<br>
<img src="cid:part1.08050500.09030102@gmail.com" alt=""><br>
<br>
I have absolutely no exception from my custom packages, so
I would like to know if any of you have the same problem.
Same exception appears with the generic editor generated
by EMF since the null pointer is really embedded into the
EClassImpl<br>
<br>
<br>
Below is the stack trace and EMF plugins versions: <br>
<br>
<img src="cid:part2.00010400.03040602@gmail.com" alt=""><br>
<br>
Any help will be greatly appreciated<br>
<br>
