Having difficulty adding child objects with Digester.addSetNext()if more than one
child exists.
Here's the xml file:
<security-constraints>
<action path="/SomeAction">
<group name="SomeGroup"/>
<!-- If I comment out this next element, it works fine -->
<group name="SomeOtherGroup"/>
</action>
</security-constraints>
Here's digester code:
------------------------------------
digester.push(securityConstraints); // this object has an
addConstraint(ActionConstraint) method.
digester.addObjectCreate("security-constraints/action",
mil.usaf.rad.dpart.struts.ActionConstraint");
digester.addSetProperties("security-constraints/action");
digester.addSetNext("security-constraints/action", "addConstraint",
"mil.usaf.rad.dpart.struts.ActionConstraint");
digester.addObjectCreate("security-constraints/action/group",
"mil.usaf.rad.dpart.struts.Group");
digester.addSetProperties("security-constraints/action/group");
digester.addSetNext("security-constraints/action/group", "add");
digester.parse("someFile");
-------------------------------------
The debug log indicates that after finding the first group it's properties are set and
it is added to ActionConstraint.
Below is what happens when digester finds the second group element and tries to add it
to ActionConstraint.

Don't want to waste anyone's time but is there something obvious that I'm missing?
Thanks,
Dave
