Re: Using Symbols

[Alessio Gambi]

Hi,

I solved this by adding the @Inject annotation. BTW, why something  
@Symbol annotation is used without the @Inject and other time they are  
coupled ?

Thanks.

Hi,

I am using Tapestry 5.0.1.5 and I have problem with using Symbols.

In a service, I need the version of tapestry currently run, so I  
injected the TAPESTRY_VERSION symbol in the service constructor (see  
the code below)

public class MyComponentEventResultProcessor implements  
ComponentEventResultProcessor

        private String tapestryVersion;
        final RequestGlobals requestGlobals

	public MyComponentEventResultProcessor(RequestGlobals  
requestGlobals, @Symbol(SymbolConstants.TAPESTRY_VERSION) String  
tapestryVersion) {
                this.requestGlobals = requestGlobals;
                this.tapestryVersion = tapestryVersion;
        }

        public void processResultValue(Object value) throws IOException {
		 
System 
.out.println("MyComponentEventResultProcessor.processResultValue()  
tapestryVersion = "+ tapestryVersion );
        ...
        }
...
}

When the service method is called, then the output in the console is  
not what I expected:

MyComponentEventResultProcessor.processResultValue() tapestryVersion  
= MyComponentEventResultProcessor


The service is used to advice the AjaxComponentEventResultProcessor:
@Match("*ComponentEventResultProcessor")
        public static void adviseAjaxRequest(
                        MethodAdviceReceiver receiver,
                        final RequestGlobals requestGlobals,
			final MyComponentEventResultProcessor  
myComponentEventResultProcessor) {

Did I do something wrong ? How can I solve/workaround this ?

Thank you.
