Hello,
i generated a model and an editor for it.
Editing files with the editor works like a charm.
But i need to edit my model when its in memory.
I am at this point:
// create a class that implements IEditorInput
class MyEditorInput implements IEditorInput
{
....
}
// start the generated editor programmatically
MyEditorInput input = new MyEditorInput(mymodel);
IWorkbenchPage.openEditor(input, "myeditorid")
My problem now is how do i need to implement IEditorInput so that when i
open the editor i dont get error messages.
How does the generated editor expects it to be? Where can i get this
information?
I dont get it...
Thank you for any hints,
Gordian

Hello,
thank you for your answer!
To answer your question: I have my model as an instance of it in memory.
Now that i know how to implement the IEditorInput Interface, i wondered
if it is possible to generate such an EditorInput class automatically.
EMF should know everything it needs to know..
Is this possible?
Thank you again,
Gordian

Gordian,
If you already have the model, then it probably already is in a resource
in a resource set. I think you'd want the editor to be initialized
quite different in this case. It's not even clear was save will mean in
such an editor. Maybe you can paint a more complete picture of the
workflow by which an existing object needs to be opened in an editor.
Consider issues like which editing domain will be used, how does the
undo stack need to be managed, and what does save verses close without
saving imply?

Hello again,
i have the following situation:
Im developing an Eclipse RCP application.
One plugin is responsible for storing and loading my model into a
database. Another plugin is responsible for displaying the data.
Im using the JFace Databinding Framework for updating the model and the ui.
Now i want to open the model editor for models that i got out of the
database.
The editor shall work as if it would operate on a file. So save - and
olny save - should update the given model. Therefore the editor would
have to make a copy of my model i think.
But thats another problem..
I would be happy get the model into the editor. No matter if changes to
the model inside the editor do change the model inside the databse. Its
just for getting started.
Could you please give me a short example or point me to the right place
on how to implement such behavior?
Thank you so much,
Gordian

Teneo solves this kind of problem. It even works with GMF...

When you load the model, you have a local copy. Until you save it, it
shouldn't be committed. Teneo supports that...

It seems to me you should be passing in a URI that represents the
information you need to connect to the data base and perhaps have a
specialized resource from loading and saving to the database. That's
the approach Teneo uses.

Perhaps Teneo provides the complete solution.
