Version 7.11.2

Patch release: B-UML export now keeps every object model in multi-object projects. A fix to the Python code builder so that exporting a class model together with more than one object model no longer silently drops the object models. No metamodel or API contract changes.

Highlights

• Multiple object models are no longer lost on B-UML (.py) export: exporting a project that combined a domain (class) model with two or more object models produced a Python file that contained none of the object models, while exporting the same project to JSON was unaffected (web editor issue #161). The root cause was in project_to_code (besser/utilities/buml_code_builder/project_builder.py): the standalone-object loop only emitted a model when getattr(om, "domain_model", None) was truthy, but ObjectModel has no domain_model attribute, so the branch never ran — and the models were also omitted from the generated Project(models=[...]) list. A single object model still worked because it took a separate one-to-one pairing path.

• The fix extracts the object-writing logic from domain_model_to_code into a reusable object_model_to_code helper (domain_model_to_code output is byte-for-byte unchanged), and project_to_code now emits every standalone object model as an object-only section that references the domain classes already written earlier in the same file. A new regression test exports one domain model plus two object models and executes the generated file back into two ObjectModel instances.

No metamodel or API contract changes.
