Howard M. Lewis Ship commented on TAPESTRY-1731:
------------------------------------------------
This is a nasty conflict between InjectWorker and InjectResourcesWorker.
InjectResourcesWorker comes first, sees the @Inject on type String and takes
over, injecting the component id.
What it should do is (somehow) recognize the @Symbol (or @Value) annotation,
and defer to InjectWorker.
Only if InjectWorker fails to perform an injection should InjectResourcesWorker
be given a crack.
However, if InjectWorker is scheduled first, then it will fail for common types
such as ComponentResources.
This will require an API change to ObjectProvider, to allow it to NOT fail if
no match may be found.

> Key: TAPESTRY-1731
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1731
> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.5
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
>
> This should work:
> @Inject
> @Symbol(WebConstants.DOCUMENT_ROOT_DIR)
> private String _documentRoot;
> But the @Symbol is not recognized, so the injection is implemented as:
> add method: private void _$write_documentRoot(java.lang.String $1)
> throw new java.lang.RuntimeException("Field
> com.dtsoft.ws.web.pages.CreateOrder._documentRoot is read-only.");
> add constructor:
> com.dtsoft.ws.web.pages.CreateOrder(org.apache.tapestry.internal.InternalComponentResources
> $1, com.dtsoft.ws.web.services.OrderDatabase $2)
> {
> _$resources = $1;
> _documentRoot = _$resources.getCompleteId();
> _database = $2;
> initializer();
> }
> This appears to be the same for @Inject @Value ... with a String type, the
> only thing that can be injected is the component id.
