RE: Question with Services (another one...)

[James Carman]

Are you using a library that's based on an older version of Tapestry?  The
getLink() method used to look like...

http://jakarta.apache.org/tapestry/3.0.3/doc/api/org/apache/tapestry/engine/
IEngineService.html

Well, thanks to Geoff I forgot to put my template (doh). Now I'm getting an
bizzarre error:

java.lang.NoSuchMethodError
org.apache.tapestry.engine.IEngineService.getLink

public Map getScriptSymbols(){
        ILink link = getService().getLink(false,this); // This is where the
error happens
        Map result = new HashMap();
        result.put("sendFunctionName", getSendName());
        result.put("receiveFunctionName", getReceiveName());
        result.put("url", link.getURL());
        if(getRefreshTimeout() != null){
            result.put("refreshTimeOut",getRefreshTimeout());
        }
        return result;
    }

            </construct>
        </invoke-factory>
    </service-point>

After debugging I found that Tapestry uses a proxy (EngineOuterProxy) for
its services. But why it's not allowing the use of the method? Am I missing
something?
