Hi,
I have a question about synchronization between Xtext editor and Sirius editor.

The sychronization between Xtext editor and sirius editor is performed by save operation. But I find when editing in the Xtext editor, perform delete opertaion in the middle of text info, then execute save operation, some elements location disappear or dislocate in the diagram edior.

After analysis, we find the relationship between diagram element and model element is index number of model member, it is stored in representation.aird. So it can explain the layout disappear or dislocation.

Is there any solution to solve the problem of layout disappear or dislocation?

Hi,

You might use eKeys in your ecore model to allow Sirius and other tools to reference your model elements with an id/name intead of the containment index.

Hi,

As mentioned by Cedric in an other post yesterday:
Quote:

a second option is to define the fragment provider for your DSL, this will have the benefit that you won't have to add back the eKeys in the .ecore when Xtext re-generates it.
Jan described the process in a blog post lately:
