Synchronization between xTtext editor and Sirius editor - location nodes [message #1768055]

Hi,

I have a question for synchronization between xTtext editor and Sirius editor.

In the xText editor, I have three nodes: Start, Operation, End. Attachment init_state.png.
If I place a new node in the xText editor at the end (after the End node), a new node will be added to the Sirius editor at [0,0] and the other nodes will remain in the same position. Attachment add_node_after_end.png and add_node_after_end.aird
If I place a new node in the xText editor at the end (after the End node), a new node will be added to the Sirius editor at [0,0], but all the other nodes that are behind this newly added node will also move to [0.0] - are lost arrangeConstraints KEEP_SIZE, KEEP_LOCATION a KEEP_RATIO. The same problem is when the two existing nodes are swapped or one of the existing nodes is deleted in the xText editor. Attachment add_node_before_end.png and add_node_before_end.aird

Do not you know how to avoid losing the position of existing nodes when adding a new node in the xText editor?

Thank you for your advice.

Martin

Hi Martin,

It seems you encounter the same issues than the following posts:
- https://www.eclipse.org/forums/index.php/t/1087235/
- https://www.eclipse.org/forums/index.php/t/1087322/

This comes from the way Sirius serialize the reference to your xtext model, with the index of elements in their containing lists, using eKeys or fragment provider should solve your issue.

Regards,

Maxime
