Hello everyone,

I'm learning to use EMF and EMF Forms, I've created my model and generated all the views.
What I want to do now is implement some checks on certain forms, for example: if the telephone number is higher than X characters, deny the input and show an error message, or, considering a class that has two references towards a certain other class, if those two references are the same, deny the input and show an error message.
Were should I start/look in order to achieve this?

Best regards.

Edit: I forgot to mention that I already tried to do this by inserting an if statement in the ClassImpl of the model plugin, but this way, it won't allow me to create an instance.
