Hi all,
In my diagram I have an element(element1) that have to be linked to
another element(element2). The palette allows me to create this element1
alone, but when I validate the model I want to display an error that tells
me to create the link between element1 and element2. The question is: how
can I write this using OCL?
Thanks and regards,
Elena

Elena,
In this case, you might not need to use OCL.
In your ecore, just set the lower bound of the EReference to "1" instead
of "0". As a result, the validation will tell you that the reference is
not set.
