Hello everyone,
I am currently working on a POC. My objective is to create a simple multi-view Eclipse RCP application enabling to load a semantic model (serialized with the standard XMI format) and display its contents as trees or diagrams or tables. I have defined the corresponding representations in Sirius's graphical .odesign editor, as explained in the 4-minute tutorial.
But in the Activator class of my design plugin (generated by Sirius at design project creation), after the following line is executed :
viewpoints.addAll(ViewpointRegistry.getInstance().registerFromPlugin(PLUGIN_ID + "/description/proto.odesign"));
then viewpoints contains only one Viewpoint object (as expected), but getOwnedRepresentations() returns an empty EList.
I don't understand why, because I defined 4 representations in my .odesign file.
I have exactly the same problem when I try to load a .aird file using SessionManager.INSTANCE.getSession() : getOwnedRepresentations() of every DView is empty.
What did I miss ?
Here are the first lines of my .odesign file (after replacing // with ||) :
<?xml version="1.0" encoding="UTF-8"?>

I don't understand either. If you debug in the method
org.eclipse.sirius.business.api.componentization.ViewpointRegistryImpl.registerFromPlugin(String)
,is the root object (a group) contained your Viewpoint (reference
ownedViewpoints) and is this viewpoint contained your representations
(reference ownedRepresentations)?
Is there any error in the error log view?

No. Are you sure that diagram plugins are available in your e4
application? Indeed the Group and the Viewpoint are concept defined in
the core plugins but Diagram representations are defined in another MM
part not in the core plugins.
Are there any successful examples of e4
> applications using Sirius ?
Obeo Designer is an application based on Sirius and on Eclipse Luna.
