Andrus Adamchik updated CAY-1988:
---------------------------------
Summary: ServerRuntimeBuilder: synthetic DataNode does not have domain's DataMaps linked (was: ServerRuntimeBuilder: created implicit DataNode does not have domain's DataMaps linked)
> ServerRuntimeBuilder: synthetic 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.
