I'm looking for a way to generate files with xpand for modeled elements only once.
In our development process a developer can define an element in the model and then start the generator which generates an java interface, an abstract class and a concrete class. The interface and the abstract class are artifacts that are completely derived from the model while the concrete class is for manual implementation of methods defined in the model.
What I want to do is to generate the concrete class once to aid the developer in creating the concrete class correct.

Is there a mechanism in Xpand that allows me to do this in a simple way without(!!!) using protected regions?

Hello Christian,

this is a very common usecase so xpand provides you a solution for that:
just use an outlet with overwrite set to false

<outlet ..... overwrite='false'/>

see section Output configuration in the docs xpand.doc/help/xpand_reference_introduction.html
