Hi,

Can somebody explain how to implement copy/paste functionality with GMF
generated diagram?

I tried this tutorial : http://serdom.szn.pl/ser/?p=6, but it fails.
When I paste a top node, a figure is displayed with a description of the
copied object between []. Do I have to add some properties to my Ecore
model ?

It seems that Logic example implements copy/paste, but domain model and
diagram are same file.

If somebody can describe step by step how to do this, it would be very
helpful for me.

Thank you very much !

Best regards,

Philippe

Hello Philippe,

To work around the problems with Copy/Paste you have to turn on "useUUIDs"
properties in the Resource implementation used for storing/loading your domain
model. One of the possible solution - use GMFResourceFactory for loading/saving
your domain model file.

Ok, I found the answer. Here is the correct procedure :

1. In your .genmodel file, set the parameter "Resource Type" to XMI.

2. Generate the source code

3. In the generated class named $MyModel$ResourceImpl (in the package
$MyPlgin$.util), you override the method "useUUIDs" like below

/**
* @generated NOT
*/
@Override
protected boolean useUUIDs() {
return true;
}

4. Generate all code (from your .gmfgen file)
5. Check if you have an extension of
org.eclipse.emf.ecore.extension_parser in your generated plugin.xml like
below :

<extension point="org.eclipse.emf.ecore.extension_parser">
<?gmfgen generated="true"?>
<parser
type="$MyDiagramNameFile$"

class=" org.eclipse.gmf.runtime.emf.core.resources.GMFResourceFactor y ">
</parser>
</extension>

Hi,

I implemented the steps in the previous post but still have a few issues
with the copy/paste.

1. The copy/paste does not work in an RCP application

2. in a non-RCP application the copy/pase functionallity allows the
diagram to be broken and exhibits strange behaviour: if i copy an element
that can exist only as a child of another element, i can paste it outside
the parent. This copy is non-unique and appears to be another
representation of the element you copied (any properties changed on either
propagate on both) but should NOT be allowed to be created in the first
place.

If anyone can please provide help on either of the above it would be
greatly appreciated,

Thanks
peter.
