Hi again,
I've read the article -- excellent reference, thank you.
I also read your suggestion with the SetNextRule, and it
makes perfect sense.
But now I'm getting a NullPointerException with the stack empty warning.
My XML is:
<a>
<b className="package.class"
attributeName="attributeValue" />
</a>
My code is:
digester.addObjectCreate("a", A.class);
digester.addObjectCreate("a/b", null, "className");
digester.addSetProperties("a/b");
digester.addSetNext("a", "addB");
But I get:
org.apache.commons.digester.Digester peek
WARNING: Empty stack (returning null)
org.apache.commons.digester.Digester endElement
SEVERV: End event threw exception
java.lang.NullPointerException
at org.apache.commons.beanutils.MethodUtils.invokeMethod
at org.apache.commons.digester.SetNextRule.end
...
Is the A element gone when the SetNextRule ends? How come?
Thanks a bunch!
