Hi,

when I have "Sequence ->first().features" if the Sequence has no element, I have "unable to access features on OclUndefined" error. What can I do?

And also in "a = Sequence -> at(1)", if the Sequence has no element, I have an error.

Hi,

You need to check first if your collection is not empty.
