------------------------------------
Summary: ServerRuntimeBuilder: created implicit DataNode does not have domain's
DataMaps linked
Key: CAY-1988
URL: https://issues.apache.org/jira/browse/CAY-1988
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 4.0.M2
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Priority: Minor
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.
