Hi all!

I'm a new user of QVTo and i'm wondering about some features inherited of the OCL standard.
In the QVT standard it says that the ordered the bag and the sequence collection type are defined. But I have tried to use sequence type whith collection operation defined in OCL but I haven't succeed to use it. I used the the completion assistant but I didn't find any clue too.

someone can enligth me please, thank you.

Hi

Completion assist is not always perfect, so perhaps that fooled you.

Sequence, Bag, Set and OrderedSet are all 'inherited' from OCL and
augmented by List and Dict. They work.

Without any example of what doesn't work for you, I can only guess:

A very common user mistake is to use . rather than -> for collection
navigation.
