Hi,
I'm trying to copy and paste single elements from a model into a new
model. Apparently it looks like it's done, since I can see a graphical
copy of that element, but if I try to save the diagram and open it back
it just disappears.
any ideas?? this is starting to drive me crazy. I haven't been able to
find any complete and clear example of a simple copy paste action on GMF.
Many people has already asked this issue on this list before me but it
seems like there aren't any convincing solution.
Please, help!
thank you!

Thanks Mario,
I'm going to take a look to the code right now. By the way, I already
came across with your presentation a few time ago and actually sent you
an email to the given address ;-), I'm not sure if you got to read it.
I'll take a look and let you know if it was of help.

Marc.

Hi Markitus,
I really struggled a long time with cut, copy & paste, especially
pasting into compartments.
From what I can tell, GMF provides everything you need and implements a
very powerful framework around copy-paste. If you see all the related
classes, its a quiet complex job.
Marios approach might also work for your use-case, unfortunately I never
got it working for my editors.
There is just two little hints, I'd like to give you:
1. Make sure to use uuids for your semantic model as described in this
post:
http://serdom.eu/ser/2008/07/02/eclipse-gmf-enabling-uuids-i n-semantic-model-the-simplest-way
There are lots of others threats in this group, adressing exactly this
issue as well.
2. Fork the class NotationClipboardOperationHelper(in plugin
org.eclipse.gmf.runtime.notation.providers)
and modify the following methods:
a)
static EObject getSemanticPasteTarget(View view) {
View parent = (View) view.eContainer();
return parent.getElement();
}
b)
private boolean shouldAllowPaste(
PasteChildOperation overriddenChildPasteOperation) {
EObject eObject = overriddenChildPasteOperation.getEObject();
EObject parentEObject = overriddenChildPasteOperation
.getParentEObject();
//implement your logic here, that checks, if eObject is allowed zo be
can be pasted in the parentEObject
}
I got the clue from this page:
http://wiki.eclipse.org/GMF_Newsgroup_Q_and_A#How_to_make_co py.2Fpaste_work_on_compartments.3F
, which contains so many useful solutions!!!
Forking basically means, you import the plugin above from the eclipse
cvs base, modify the code and use your customized plugin for your
application, rcp or whatever. (just in case you struggle with the term,
like I used to)
Let me know, if you need any further help.
HTH

Thomas

Perhaps I misunderstood or I missed something. But wouldn't the result be

implements IClipboardSupport) and rewrite these methods?
Anyway, I'm clearly confused, as you see.
My problem is not pasting into compartments , I didn't even get that far
yet :( . I've enabled the copy/Paste option so it shows up in the
contextual menu. I'm being able to copy or paste whatever elements I want
to(graphically), but when I try to make these changes persistent these
new copied elements simply disappear. Even if I add an original object
from the palette after a copy/paste action, the previously copied
elements disappear from the canvas. It is so weird!!
So I'm not sure if i have to rewrite anything since I'm not trying to do
anything special, just a simple copy paste action with simple elements
(not compartments).
Should I expect this to work straight, or should I rewrite some code ?
Thanks for your help.
Marc.

Hello Marc,
it seems you have the same problem I had (and still have). The point
is, that the elements do not disappear after they have been copied, but
that only their views are copied, I guesss. To verify this, please
copy-paste an element and then modify it. If I'm right, the original
element will get changed, too.
However, this is not a solution to your problem (I wish it were, as then
my problem would be solved as well), but maybe it gives you some idea of
where to begin. For me, I tried a few days to solve it before I finally
gave up... :-(
Regards, and good luck,
Tobias

So first of all:
Did you both make sure to use uuids for your semantic model as I
described earlier in step 1?
If so, copy paste should at least work for elements placed directly on
the canvas.
So you must add the following extension to your plugin-xml:
<extension point="org.eclipse.emf.ecore.extension_parser">
<parser type="MY_SEMANTIC_MODEL_FILE_EXTENSION"
class=" org.eclipse.gmf.runtime.emf.core.resources.GMFResourceFactor y ">
</parser>
</extension>
Where MY_SEMANTIC_MODEL_FILE_EXTENSION seriously only is the
file-extension of your editor-files.
Step 2 was the solution to make copy/paste work in compartments
(container-elements).

Hi Thomas,
I did exactly as you said (step 1). Actually it was already done before I
started trying to copy paste. I'm getting the same errors as Tobias. If I
change smth in the new copied element, whatever change I do on this new
element, is reflected on the original too. So there must be some base
errors that leads us to this behavior.
I can't understand why it's behaving like this, and for sure I don't want
to give up ( I can't ), but it's really starting to be quite
discouraging. It seems so obvious that it should SIMPLY work...
good to know, Tobias, that I'm not alone in this fight!

the behaviour you describe sounds to me like you are using shortcuts,
not real copies of elements.
How do you create your copy?
Select -> <Ctrl> + <C> -> <Ctrl> + <V> ?

Weird weird weird. I guess it has something to do with the original
creation of the ecore. The thing is that the development of this app
started around 2 years ago, and perhaps it's a bit too late to start back
again from scratch.
thanks for your help.
REGARDS,

Hi Marc,
unfortunately I ran into the same problems, recently. Copy/paste
basically works - meaning I am able to copy compartments and components
from one compartment to another (visually). If I modify properties of
the copied component/compartment, the source-component/compartment is
changed too. After reopening the diagram file, all copied elements
disappeared, although they are still visible in the generated xmi-file.
I am already using uuids.
Did you already manage to get copy/paste working? Any hints?
Thanks in advance,
Daniel

Hi Daniel,
I'm afraid I don't have good news for you. I just gave it up. I didn't
get any closer, I tried to update all the emf/gmf plugins but it didn't
work out after all. I'm sorry.
I'm just back here to find a solution but it looks like i was the last
one asking about this. I spent a great amount of time attempting to
copy / paste but I didn't even take a single step forward. I don't want
to discourage you but I wouldn't waste much time with this.
anyway, good luck!! and of course, if you manage to solve it, tell me
how! ;)
cheers,
marc.
