I'd like to provide a new SymbolSource service without the cache
functionnality in order to allow me to change the value of severals of
my symbols.
My problem is that I can't define a new implementation of SymbolSource
interface (like this :
p_Binder.bind(SymbolSource.class,FwlSymbolSource.class).withId("FwlSymbolSource");
) because Tapestry throw me the following exception (I've attached the
whole stack)
/java.lang.RuntimeException: Service interface
org.apache.tapestry5.ioc.services.SymbolSource is matched by 2 services:
FwlSymbolSource, SymbolSource. Automatic dependency resolution requires
that exactly one service implement the interface./
Maybe it's impossible to provide another implementation for this service
interface...
Regards,
Julien.

hi Julien,
the default SymbolSource is qualified by the @Builtin marker...
eg.:
... build(@Builtin SymbolSource t5SymbolSource)....
are you trying to replace the whole SymbolSource service?

Re: [T5] Create a new SymbolSource service
Kristian,
thanks for your reply.
I've already qualified my new implementation of the interface
org.apache.tapestry5.ioc.services.SymbolSource like this :
/p_Binder.bind(SymbolSource.class,
FwlSymbolSource.class).withId("FwlSymbolSource");/
However the "default" implementation of this interface is defined in
TapestryIOCModule class without a service Id.
Regards,
Julien

hi Julien,
if you want to define two (or more) services with the same
interface you have to qualify them.
if you use the binder method:
public static void bind(ServiceBinder binder)
{
binder.bind(SymbolSource.class, MySymbolSourceImpl.class
).withId("mySymbolSource");
...
or as builder method
public SymbolSource buildMySymbolSource(...) {}
everytime you want to inject your service you'll have to
qualify it as well:
public Interface build(@InjectService("mySymbolsource") SymbolSource
mySymbolSource)
{}
i hope this helps.

[T5] Create a new SymbolSource service
Hi everyone,
I'd like to create a new service implementing the interface
*org.apache.tapestry5.ioc.services.SymbolSource* to remove the cache
functionnality of the Tapestry service *SymbolSourceImpl*.
However I can't create such a service because I've the following
exception :
/Service interface org.apache.tapestry5.ioc.services.SymbolSource is
matched by 2 services: FwlSymbolSource, SymbolSource. Automatic
dependency resolution requires that exactly one service implement the
interface./
Can I prevent this problem ?
Regards,
Julien
