Sirius web representationId [message #1853480]

Hello,

I'm trying to follow the recent example from EclipseCon with the creation of a new type of representation.

I'm not sure how to set the id of the created representation.
After creating it, I have this message :
o.e.s.c.c.e.EditingContextEventProcessor : The representation with the id xxxx does not exist

I tried to set the id with createRepresentationInput.getId().toString() but it seems that theEditingContextEventProcessor is registering a different id.

It's up to each representation implementation to create the id of a new instance.
For example for diagrams it is determined here. It's a random UUID for a newly created diagram, and if its a new version/refreshed state of a previously existing diagram we reuse that.

The id associated with CreateRepresentationInput.getId() is the id of the input event itself. It is only useful as a correlation id between an input event and the payload(s) returned to the frontend.
