Hi all,

I'm new to ECF.

I intend to built a shared whiteboard Eclipse RCP application using ECF
and GEF. I successfully tested the XMPP MUC with wildfire as XMPP server.

But I have a problem with the shared editor example:

when I go to the Team -> ECF Editor Shared preference page, I get a
preference page creation problem, "plug-in org...collab.editor was unable
to instantiate class org...ClientPreferencePage",
with a NullPointerException

I checked the .log file but there doesn't seem to be any reference to this
exception..
------------
!ENTRY org.eclipse.ecf.example.collab 0 0 2006-05-16 10:36:20.31
!MESSAGE ECF: Autostarting
containerType=ecf.xmpp.smack,uri=denis@liristpm.univ-lyon1.fr,nickname=
--------------

I use org.eclipse.ecf.sdk-0.8.0.S20060507.zip
and emf-sdo-SDK-2.1.2.zip

any idea ?

thanks for your help

Hi Denis,

I'm currently not able to reproduce this NPE with the preference page
creation with ECF 0.8.1 (just put out on Sunday) on Eclipse 3.2rc2. But
I don't think it's an ECF version issue, as I don't think anything about
the collab editor example changed from 0.8.0 to 0.8.1.

Does the NPE happen every time you go to the preference page? If not,
what conditions lead to it appearing?

What version of Eclipse are you using?

Thanks,

Scott

Hi Scott,

I'm using eclipse 3.1.2 (with Java 1.5)
It happens every time I go to the preference page.

Hi Denis,

I suspect, then, that there is something about this preference page that
is 3.2 specific.

I've filed a bug for this at:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=142040

We will try to maintain backward compatibility with 3.1.2 for a couple
more months, but when 3.2 is released (June 20something) we'll probably
lose any 3.1.2 backward compatibility at that time.

Denis if you could use 3.2M6 or newer (currently on 3.2rc4) I think you
would not have this problem. If you can't do that, we'll try to get the
fix in for 0.8.2 (this sun, May 16).

Thanks,

Scott

Hi Denis,

I've verified that this bug exists for 3.1.2 (not for 3.2x stream). It
seems to be something not allowing the preference page to be created.

Denis is it possible for you to use 3.2M6 or newer? I would like to
avoid a lot of work to back port the example applications if at all
possible.

Please let us know.

Thanks,

Scott

dear Scott,

yes sure, no problem.
I am updating my eclipse install right now to the latest 3.2 milestone.

Thanks for your help :-)
(sorry for my late answer)

Denis.
