SymbolSource to clear cache
Hi everyone
Is there a possibility that a method is added in SymbolSource in order
to clear its caches.For example if i add a databaseSymbolProvider and
i want to updatesymbol values from the application i cannot do it
right now because the symbols are cached inside symbolSource.Maybe if
we can have a method to clear the cache or better pass symbolprovides
rid and only clear that it will be much better
Best Regards

I do. Symbols have been immutable for years, since the beginning of
Tapestry 5, and changing that would have unforeseen consequences. Nothing
that uses symbols nor SymbolSource nor SymbolSource expects them to
change. If you want something that is mutable, just create your own
service for that. SymbolSource reads all symbols provider values at start
up and never reads them again, so clearing one of the providers wouldn't
make any difference.

Symbols are meant to be immutable, so I doubt it will ever happen.
