Restrict properties in diagram editor. [message #221472]

Hi all,

I have produced two GMF diagram editors that are based onto the same Ecore
metamodel definition.

The first GMF diagram editor allows to define models that are selected (1
or more of them) accordingly by the user and loaded as required when a new
model is created with the second GMF editor. Therefore the second GMF
editor opens up with the existing model instance loaded directly from the
xmi specific files.

I would like to know if there is a way to restrict the changes that can be
made to the loaded model instances. For instance assign some properties to
be read-only when loaded, or take specific values. This could be achieved
for example if I assign something like enumerations to those properties in
the first GMF editor?

The bottom line is to use the models defined in the first editor as
templates in the second editor and extend the model definition accordingly.

I hope it is clear what i am trying to achieve. PLease if you have any
suggestions on how to achieve this are more than welcome.

Thanks,

Achilleas

Hi,

I am short of solutions on this aspect. Let me repeat on what I am trying
to achieve.

I have two GMF editors based on the same metamodel. I use the first GMF
editor to define parts of a larger model that are saved into individual
resources; which I consider as templates. Then I have extended the wizard
so I can preload these templates, when the new model is initialised in the
second GMF editor.

Therefore the second GMF editor allows to use those templates and add
additional elements to construct the final model. What I want to know is
if I can declare the values of the template elements to be read-only or
have a fixed range of values when these are loaded in the second GMF
editor.

I hope I could explain properly what I am trying to achieve. Any ideas
will be greatly appreciated.

Thanks,

Achilleas
