Opening the menu on Edit click, would not offer this choice :
"capellamodeller::SystemEngineering "
It appearts to me that is it offering only variables types which are “lower level” than the starting variable Type (which is here : la::LogicalArchitecture)
It seems i must make a new template in order to be able to choose this “variable Type”.
The list of available types is build with the list of declared nsURIs in the template. You can modify this list using the template properties wizard. In your case you should add something like:
The version number might change depending on which version of Capella you are using.
An option could be added to the type selection dialog to list all types available in the environment and then add the nsURI automatically if missing. I opened the following issue.
