Greetings

I am running a GroovyScript that has the following code:

...

         def holder = groovyUtils.getXmlHolder( it.name+"#Response" );
         if (holder["//ns1:FunctionReturnCode"] == "SUCCESS") {
...

The issue is the #Response may or may not be there.  Therefore I am getting a NullPointerException.  This, for one, locks up my system for about 20 minutes while it does something ... However, I want to know how I can check for a valid response without getting a nullPointer?

Is there a check I can run.  I looked at the API for xmlHoder but I cannot find anything.

Thanks,
Jb
