Hello,
Here is my dumb quest: I am trying to understand GEF using the latest
version on Eclipse 2.0.1,
then I try to see what I can port to GEF 1.0 with is part of the
commercially available WSAD 4.0.3...
Why? because it will take a good while until all WSAD 4.0.3 customers
migrate to WSAD 5.0,
and further more, if GEF in WebSphere Studio Workbench 2.0.1 reflects the
version
in WSAD 5.0 GA, then we are in trouble anyway developping with latest GEF,
because
refactoring of com.ibm.etools.gef into org.eclipse.gef (and other similars)
have not happend.
I guess I am not alone (in the dark ;-). Feel free to join me in this dumb
man's quest!
So, until now I have succeeded into creating a minimal GEF 1.0 editor blank
page that work with WSAD 4.0.3.
I just do not understand why the compiler barks on
com.ibm.etools.gef.ui.parts.GraphicalEditor
being deprecated.
If it can help, here is a snipped of my GEF 1.0 working "blank GEF" editor.
It does nothing but openning a GEF editor in which you can click & drag the
mouse to draw nice selection rectangles ;-) Note that the commented code
with "Eclipse 2.0" means deleted code that used to work with latest GEF
version...

If you are targeting WSAD 5.0, you can use either the GEF found in WSWB 2.0
(which is com.ibm), or you could use org.eclipse.gef. You should pick
whichever one suits your needs. WSWB 2.0.1 is immediately available. The
ORG.eclipse.gef version is not yet available, but will have additional
features. What is the trouble you are talking about? When org.eclipse.gef
is released, you can redistribute it into WSAD 5.0, and it will work.

Randy:
It is not the first time I read in this newsgroup your answer to similar
question:
Each time somebody tries to run GEF on WSAD 4.0.3 or WSWB 1.0 or Eclipse
1.0,
your answer is to switch to Eclipse 2.0.x or wait for WSAD 5.0
While I understand that you don't want to maintain older GEF versions, the
logical
diagram editor example that used to work with Eclipse 1.0, WSWB 1.0, WSAD
4.0.3 shows
that a great deal of graph UI can be acheived with *currently deployed
software*.
Switch from Eclipse 1.0 to Eclipse 2.0 is easy, but switch from WSAD 4.0.3
to WSAD 5.0
will likely take much more time because:
- companies that bought WSAD 4.0.x and deployed it for production use are
likely to want to throughly WSAD 5.x on non-crital projects until they
are confident
with this new release... and you know IT decision makers rule: never
trusts a x.0 release ;-)
- some companies will not migrate from WSAD 4.0.3 to WSAD 5.x at all: either
because
they don't see the interest of paying the for a new version if current
version works for their
needs ; or more often because they developped a big piece of software
with WSAD 4.x
that they want to keep for application maintenance purposes, they don't
even want to
to try WSAD 5.x to see what impacts it could have on their deployed
application (if it
runs, don't break it)
Eventually, WSAD 5.x will have its customer base, but for developpers who
want (or are
asked) to bridge the gap between WSAD 4 and WSAD 5, trying to run GEF 1.0
despite
lack of new developments on GEF 1.0 core itselves may be worth.
Does it makes sense to anybody else reading this newsgroup? please, react!
Alex.

I wasn't responding to your comments about WSAD 4.0.3 and WSWB 1.0. I was
responding to your comments about WSWB 2.0.X, and WSAD 5. Specifically:

I thought you were saying that *IF* you were developing for WebSphere Studio
Workbench 2.0.1 that you would be in trouble because GEF is still com.ibm in
that product. It is still com.ibm, and that won't change until later, but
there is no reason that you couldn't distribute org.eclipse.GEF onto
WebSphere Studio Workbench 2.0.1. That was my point, that you could use the
new GEF with WSAD 5.
As far as WSAD 4.x.x and new GEF features, this won't happen. For similar
reasons, IBM won't [I'm speculating] be adding any new features to WSAD 4 or
upgrading their EJB support to new levels of the Spec.
But seeing as how GEF is now distributed under open-source, there is no
reason that you couldn't take org.eclipse.gef 2.?.?, and back-port it to
WSAD 4.x.x. This should be easy. The only ramifications would be that you
would have to make the port available to the public.

Ahhhh.... very astute solution indeed!
Let me think about it... I need to investigate "how easy" it could be.
Thank you very much
Alex.
PS: <joke>you have such a gift to return people's expectations into
something like "instead of asking what the [open source] community can do
for you, try doing it for the community ;-)" Have you ever tried to do
politics? </joke>
