Kirill Tkalenko updated IGNITE-16295:
-------------------------------------
Description:
At the moment, listeners *any()* for a polymorphic configuration do not get
specific instances, but general ones.
The following example will clearly show the problem:
{code:java}
@Config
public class TableConfigurationSchema {
@NamedConfigValue
public BaseIndexConfigurationSchema indexes;
}
@PolymorphicConfig
public class BaseIndexConfigurationSchema {
@PolymorphicId
public String type;
}
@PolymorphicConfigInstance("hash")
public class HashIndexConfigurationSchema extends BaseIndexConfigurationSchema {
@Value
public String column;
}
@PolymorphicConfigInstance("sorted")
public class SortedIndexConfigurationSchema extends
BaseIndexConfigurationSchema {
@Value
public String column;
}
...
rootConfig.tables().any().listen(ctx->{
// It's falling here.
assert ctx.newValue() instanceof HashIndexView;
return CompletableFuture.completedFuture(null);
});
rootConfig.tables()
.change(c->c.create("0",c1->c1.convert(HashIndexChange.class).changeColumn("idx")))
.get(1,SECONDS);
{code}
