Re: Make DefaultComponentMessagesSource more flexible to subclass
Umm.... I just want to leverage most of the functions the DefaultComponentMessagesSource.
I consider most part of DefaultComponentMessagesSource is quite good for common implementation... the cache and the fallback to higher level of locale.
If I take decorator pattern containing an instance of DefaultComponentMessagesSource, can I leverage these without copying all of those code? Ummm.... maybe that's the problem of my skill and out of this topic.
PS. Somebody here has suggestion to me? Thanks in advance. :)
Best Regards,
Alex.
