Hi,

when building a metamodel, -1 symbolize the maximum value in a EAttribute.
But whenever I want to make a test on a EAttribute, if I want to check if it's value is higher than 12 (for example), I need to make two tests, in case the value is infinite (-1).

attribute > 1 || attribute == -1

It is more for beauty than a necessity, but is there an extension that does both tests, or would I have to write it.

Hi Maxime,

EAttribute has a property 'many'. I think this is what you search for.

Regards,
