[jboss-user] [JBoss AOP] - Write invocation not being called for arrayreplacement

[sgoyette]

Hi All,

I've been pulling my hair out with this one for some time.  I'm trying to intercept reads and writes to an array.  Reading is working really well but I cannot for the life of me get the writes to work.  Here's is mu jboss-aop.xml file:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <aop>
  |    	<interceptor class="com.intuit.tax.engine.group.TSingleGroupInterceptor"/>
  |    	
  |    	<arrayreplacement class="com.intuit.tax.engine.group.TSingleGroup" />
  |    	<prepare expr="field(* com.intuit.tax.engine.group.TSingleGroup->R)"/>
  |    	<prepare expr="field(* com.intuit.tax.engine.group.TSingleGroup->B)"/>
  |    	<prepare expr="field(* com.intuit.tax.engine.group.TSingleGroup->S)"/>
  |    	
  |    	<arraybind type="READ_WRITE">
  |        <interceptor-ref name="com.intuit.tax.engine.group.TSingleGroupInterceptor"/>
  |    	</arraybind>
  | </aop>
  | 

This calls this function within the TSingleGroupInterceptor:


  | 	public Object invoke(Invocation invocation) throws Throwable {
  | 
  | 		List<ArrayReference> refs = ArrayRegistry.getInstance().getArrayOwners(invocation.getTargetObject());
  | 		logger.debug("Owner is " + refs.get(0).getRootObject().getClass().getName() );
  | 		
  | 		// These objects should only have a single owner
  | 		TSingleGroup group = (TSingleGroup)refs.get(0).getRootObject();
  | 		if ( invocation instanceof ArrayElementReadInvocation) {
  | 			logger.debug("Read invocation");
  | 			return invoke((ArrayElementReadInvocation) invocation, group);
  | 		} else if (invocation instanceof ArrayElementWriteInvocation) {
  | 			logger.debug("Write invocation");
  | 			return invoke((ArrayElementWriteInvocation) invocation, group);
  | 		}
  | 		logger.debug("No match for read/write.  Invocation is: " + invocation.getClass().getName() );
  | 		throw new RuntimeException("This interceptor is for arrays");
  | 	}
  | 

Write invocation is never logged and neither is "No match for read/write".

What am I doing wrong?  Can anyone help?

Thanks,

Steve
