I often have the requirement to copy over a subset of attributes from one object to another (having the same type).
It would save time and avoid errors when there was a special copy-attributes/associations activity that allows to:
* select source and target object (of same type? or even better all attributes that have matching name+type)
* select all attributes and associations that should be copied (checkboxes)
As a bonus when new attributes are added to the domain model there should an option to generate errors for all theses activities unless the developer decides whether or not this new attribute is also copied or not (similar to what we have for enumerations when they are used in conditional visibility).
