Subject [jira] [Commented] (EXTVAL-137) Deregistering a class from the NameMapperFactory results in unsupported operation on CopyOnWriteArrayList
Date Wed, 02 Nov 2011 15:17:32 GMT

    [ https://issues.apache.org/jira/browse/EXTVAL-137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142205#comment-13142205

Rudy De Busscher commented on EXTVAL-137:
-----------------------------------------

There exists in many cases a workaround to define an appropiate InvocationOrder annotation
on your custom NameMapper so that it is tried as the first NameMapper.

@InvocationOrder(value = 1)

> If you wan't to deregister a NameMapper from the Factory class, so that it isn't used
in your application, you get an exception because (some) factories use a CopyOnWriteArrayList
List implementation.
> For example
>         ClassMappingFactory factory = ExtValContext.getContext().getFactoryFinder()
>                 .getFactory(FactoryNames.STORAGE_MANAGER_FACTORY, ClassMappingFactory.class);
>         NameMapperAwareFactory nameMapperFactory = (NameMapperAwareFactory) factory.create(ProcessedInformationStorage.class);
>         nameMapperFactory.deny(ProcessedInformationStorageNameMapper.class);
>         // Code omitted to add the custom nameMapper
