I have created a model with EMF and I would like to be able to save my model with the editor and open it later. For the example let's say that my model has 3 classes: A, B, C and R. The R is the root parent. The class C has a reference to A and one to B. When I edit my model everything works fine. But if I want to save my file to another location, I can open it but I can't save it anymore without getting an error message telling me that my references in my C object are dangling references. The xml file when saving looks like this for my reference:
<refToA ="//@CompElement.0/@composit/@parts.0">
I tried to set containable to true in my ecore file. Dangling references disappear but after a save if I touch attribute of B that the changement doesn't apply to the reference because now I have two B object.
How can I make properly a reference and save it ?
my model has 3 classes: A, B, C and R
you mean your metamodel has 3 EClasses/metaclasses A, B, C and R.
The R is the root parent
The root element of your model is of type R. How are A, B and C contained?
When I edit my model everything works fine. But if I want to save my file to another location, I can open it but I can't save it anymore
I doubt simply saving your Resource to a location or another has a significant impact on your model. How are you editing it and saving it to another location?
I found the solution. in my XMI file model was saved like this :
<R>
<C refA... refB...>
<\C>
<A><\A>
<B><\B>
<\R>
reference need to be place after saving A and B object like this :
<R>
<A><\A>
<B><\B>
<C refA... refB...>
<\C>
<\R>
