Hi,

I have very simple ecore model where "general" class has a derived varible "var" of type DOUBLE and has an operation "operation" of DOUBLE.
Class "special" is extending from "general" and "operation" is also overriden.

Please open given ecore file in Sample Ecore Editor(JUNO)

Right click on "Connector" and select "Create dynamic instance" of Connector and all some children(special and general).

For "general" objects, the value for variable "var" is correct but for "special" objects value of "var" is not calculated.

import ecore : 'http://www.eclipse.org/emf/2002/Ecore#/';

package temp : EAAT = 'http://www.eclipse.org/mdt/ocl/oclinecore/tutorial'
{
class special extends general
{
operation operation() : ecore::EDouble { ordered }
{
body: 3.5;
}
}
class general
{
operation operation() : ecore::EDouble { ordered }
{
body: 2.3;
}
attribute ID : ecore::ELongObject { ordered };
attribute name : String { ordered };
attribute var : ecore::EDoubleObject { ordered derived volatile }
{
derivation: operation();
}
property connector#general : Connector[*] { ordered };
}
class Connector
{
attribute ID : ecore::ELongObject { ordered };
attribute name : String { ordered };
property general#connector : general[*] { composes };
}
}

Hi

Thanks for the clear repro.

This has been fixed by my recent rationalization of the merged/raw
meta-models.

If you install
http://www.eclipse.org/modeling/download.php?file=/modeling/mdt/ocl/downloads/drops/4.1.0/N201209061453/mdt-ocl-Update-tools-N201209061453.zip
you should pick up the fix.

Regards

Ed Willink

Hi,

Is this fix is also suitable for Indigo when not using pivot model?

Actually i want to use Indigo and want to have this bug fixed.

Cheers,

Hi

All Kepler builds should be useable on Indigo.

thanks!

I have just tried this and it only works in case of Pivot model, if models delegates are not based on pivot then it does not work.

Do you have any why it is like that?

Hi

The Juno release redesignates the .../OCL delegate URI as a virtual
which can be redirected to LPG (the old Ecore implementation) or Pivot
using Window->Preferences->OCL.

thanks.

When i try to update my indigo with given fix then it says
"
Cannot complete the install because one or more required items could not be found.
Software being installed: OCL End User SDK 4.0.0.v20120906-1453 (org.eclipse.ocl.all.sdk.feature.group 4.0.0.v20120906-1453)"

i did it on JUNO successfully but on indigo it is problematic.

any clue?

Cheers,

Hi

You don't identify what's missing which makes diagnosis harder.

There is a problem with feature name compatibility between the Core and
Tools builds that prevents upgrading the full Tools byuild after a Core
build has been installed.

The easiest way to upgrade is uninstall all OCL artefacts then intall
OCL Examples and Editors.

Installation problem is fixed.
I have now tested and verified that method overriding bug is only fixed for Pivot not for old Ecore implementation. Can you also confirm that?
In this case is there any fix available for old Ecore implementation.

I really appreciate your efforts.
thanks

Hi

The code is thought to work as intended.

Can you clearly identify a scenario that does not; preferably as a
zipped project.

Hi,

Here comes a scenario where i have created an ecore model(the one we have discussed earlier in this thread).

I have also taken dynamic instance of one of the concept in Ecore.

"General" and "Special" has a method "Operation" and it is returning real value.

"Genrel" contains attribute "var" and it derivation statements depends on method "operation".

Please check this scenario.

Hi<br>
<br>
For compatibility the Ecore-based OCL retains the legacy no
overloading functionality.<br>
<br>
You may enable overloading in the
Window-&gt;Preferences-&gt;OCL-&gt;ECore and UML<br>
<br>
<img src="http://www.eclipse.org/forums/index.php?t=getfile&amp;id=12069" alt=""><br>
<br>
(Sorry. Forgot that we had fixed the 'bug' but also preserved
compatibility. It's not a bug because the OCL specification has no
indication that dynamic overloading should be used.)<br>

Thanks alot.

I am using deletgates to evaluate so is there any mechanism for delegates to achieve the same?

Hi

You still have to set the option on the environment.

You might need to use custom Delegate Factories to intercept the
environment creation.
