Return a set of Tuple in OCLInEcore editor [message #1241116]

Hello everyone,
When defining an operation returning a set of tuples using OCLInEcore editor like this:

operation createTupleSet() : Tuple(name : String, alias : String[*])[*] {ordered}

, the return type is always considered as Void and thus, I've always got the following error:
Quote:

An operation with void return type must have an upper bound of 1 not -1

. Would you mind telling me what is the proper way of declaring an operation with the return type containing Tuples?

Best regards,

Hi

It works fine for me on the development branch.

What version are you using?

Try using a Luna milestone release that should be installable on Kepler.

Hi Ed,
I've got the following errors while trying to install OCL-5.0.0M5 from OCL Milestones Repositories:

Quote:

An error occurred while collecting items to be installed
session context was:(profile=epp.package.standard, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
No repository found containing: org.eclipse.update.feature,org.eclipse.ocl.master,5.0.0.v20140124-1452

By the way, the problem is not solved with OCL-4.2.0M4 and Eclipse Luna, on my computer. Would you mind checking on this issue?

Many thanks,

For more information, a simple ecore model like this:

package test : test = 'http://test.fr/test/1.0'
{
	class Test
	{
		operation createTupleSet(): Tuple(name : String, alias : String[*])[*] {ordered}
		{
			body: null;
		}
	}
}

would cause the following validation error on createTupleSet if the model is opened using the Sample Ecore Model Editor:

Hi

I'm totally confused.

This is a thread about a semantic error but you comment on an
installation error. So I ignore both.

Hi

Sorry

https://bugs.eclipse.org/bugs/show_bug.cgi?id=401938#c5

shows that more work is needed to support persistence of OCL Tuples in
an Ecore environment.
