Hi list,
I have an optional configuration encoded inside a symbol.
I inject the symbol using the annotation (pseudo code below).
@ServiceId("TheService")
public ... build(
... ,
@Symbol("the-optional-symbol") File optionalFile,
... ){
}
When I do not provide the symbol (it's an optional configuration) and build the
service, I got the following exception:
[ERROR] 11:05:05,966 Registry.log: [ 4] Resolving object of type java.io.File
using MasterObjectProvider
org.apache.tapestry5.ioc.internal.OperationException: No service implements the
interface java.io.File.
While I expected somehow to get a null value injected (or at least an exception
from the SymbolSource).
I known that I can inject SymbolSource and manage manually the case, however I
prefer the framework to do that for me ... if possibile.
My question then is:
Is that really possible to inject a "non-provived symbol" ?
