[news.eclipse.modeling.m2m] Re: [ATL] result of undefined subSequence ca

[Loïc Fejoz <loic.fejoz@xxxxxxxxxxxxxxxxxx>]

Hi,

I opened bug #289416.

I look at the UML 2.0 OCL Specification (in the semantic part), it 
should be oclUndefined. In MDT/OCL, they choose to return null (see bug 
#244946 [2] and the discussion [3]).

Anyway both virtual machine are not consistent...
