All layers are equal (or not?) [message #1790858]

Hi,

My user noticed that the visibility of some of my layers wasn't persisted with the diagram. Furthermore, he noticed that the layers, whose visibility state was not persisted, were grouped below a separator line.

I noticed that these layers don't have any visualizations. They only contain decorations and some tools.

Is this intentional or did I trigger a bug?

I attached a (somewhat obfuscated) image of the layers menu. The lowest two layers are separated from the others as described above.

Greetings,
Wilbert.

Hi Wilbert,

Yes, it is intentional. Transient layers (see https://www.eclipse.org/sirius/doc/specifier/diagrams/Diagrams.html#layers) are intended to display additional decorators without modifying the diagram. They can be activated or deactivated by default.

Regards,

Florian

Hello

A layer is considered as transient if it contains only tools or decoration. If you want to persist the layer activation you may, as a workaround, add a fake node mapping without id.

We aim to add an attribute on the layer to know if it is layer or not, but I have no target release to give you at this time.

Regards
Laurent
