Description

A project consisting of a single DataMap with no mapped DataNodes is loaded as follows:

return new ServerRuntimeBuilder()
.addModule(binder -> binder.bind(SchemaUpdateStrategy.class).to(CreateIfNoSchemaStrategy.class))
.jdbcDriver(driver).url(url).addConfig("cayenne-project.xml").build();

When CreateIfNoSchemaStrategy is invoked on startup, it generates exactly zero tables. When digging deeper I noticed this is caused by SyntheticNodeDataDomainProvider failing tolink any DataMaps to the "synthetic" DataNode from the parent domain. So CreateIfNoSchemaStrategy has nothing to work with.

The workaround is probably to create a dummy DataNode in the project. But it is not very clean.
