[EMF Compare] "Copy current change from right to left" doesn't work? [message #506112]

Hi,

I am a new user for EMF compare. I just do a simple test.

Base model is one class.
Then User1 add one attribute: Property1:EInt.

Then I use EMF compare each other, at this time, base model is on left side, and User1 is on right side.

When I click "Copy current change from right to left" button to merge from right to left, it doesn't add same attribute on left model. On left model, just one attribute named as Property1, but has no EInt type!

Is this normal behavior?

B.T.W, if I want to extend "Copy current change from right to left" button action, how to develop? I means what extension point should i extend?

Thanks!

Hi,

Nope, this is no expected behavior; though we've never experienced this
ourselves and I cannot reproduce your behavior with sample models with
the steps outlined here.

This seems to be fixed with the latest vesion of EMF Compare. Which are
you using?

Extending the merge actions is not possiblve apart from providing your
own mergers. This is done through the extension point
org.eclipse.emf.compare.diff.mergerprovider .

Hi

First thanks for your quick reply.

But actually I meet this merge problem. It is a simple ECore model.

Left is empty class, right is a class with "Property1:EInt", when merge from right to left, left only get Property1 name, no Eint.

I just select two ecore files, and then compare with each other, then that problem happen. I dont know whether my operation is corrent or not.

If possible, I can upload a screenshot. I use eclipse-modeling-galileo-SR1-incubation-win32 package. It seems that EMF compare version is V1.0.1.

Thanks!

Hi,

The samples I used to try and reproduce are exactly what you describe :
an empty EClass on the left, the same EClass with the addition of an
attribute "property1 : EInt" on the right, then merging from right to left.

This operations yields the expected result of an EClass with "property1
: EInt" on the left after merging. Thus the question I asked : which
version of EMF Compare in which Eclipse are you using?

Hi,

Yes, this is a really strange problem.

Today I download "org.eclipse.emf.compare.examples.standalone" example from CVS repository. and then compile and create a runnable JAR file which name is EMFStandalone.jar.

Now left model is My.ecore as
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="my"
nsURI="http://my/1.0" nsPrefix="my">
<eClassifiers xsi:type="ecore:EClass" name="EClass0"/>
</ecore:EPackage>

Right model is My1.ecore as
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="my"

<eStructuralFeatures xsi:type="ecore:EAttribute" name="EAttribute0" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EInt"/>
</eClassifiers>
</ecore:EPackage>

Then I run command as:
[brucehuang@rat013:/sandbox/bruce/EMF]$ ls
EMFStandalone.jar My1.ecore My.ecore
[brucehuang@rat013:/sandbox/bruce/EMF]$ java -jar EMFStandalone.jar My1.ecore My.ecore

<leftRoots href="My1.ecore#/"/>
<rightRoots href="My.ecore#/"/>
</diff:DiffModel>

saving emfdiff as "result.emfdiff"

Then I see My.ecore again, it has no change as before. I don't change any on "org.eclipse.emf.compare.examples.standalone" source code.

So why? Is there some wrong with source code?

And also I use the above two model to merge using graphics method, it fails as I describe before. Sorry to disturb you.

Hi,

I am using EMF Compare 1.1.0 v200912150654, and then it seems that "copy current change from right to left" button works, but when it fails to save. And one nullPointer exception is caught. I report one bug 299214.

And before I use EMF compare 1.0.1 v200909161031.

Thanks!

Hi Bruce,

IIRC, the standalone example does not save any model after merging
operations took place. You have to save the merged model yourself.

Hi Bruce,

This had been previously identified and the fix is already commited.
This failure will disappear from the next build onward.

Hi Laurent ,

Thanks for your great help.

B.T.W, it seems that EMF Compare 1.0.0 has "Draft Graphical Modelers Integration " feature from http://wiki.eclipse.org/EMF_Compare_1.0.0_New_And_Noteworthy #Draft_Graphical_Modelers_Integration.

But when I compare two *.ecorediag file each other, no Graphical Compare window appear, so what is wrong with it? Is this feature unavailable currently?

And also if I use Topcased Plugins to create two UML models, and two responding *.umldia file, is it possible to compare two *.umldia file in Graphical Window way?

Thanks very much!

Hi Bruce,

the graphical modelers integration feature is not provided as built plugins
and is only available through CVS right now.

Once built and installed it should work with any GMF based diagram model, as
such it should work with EcoreDiag (like in the demo) but not with Topcased
ones as topcased is not based on GMF.

Cheers,

Cédric
