Or, save a lot of the complexity and instead of binding your
hyperlink/button to the displaygroup.displayNextBatch, create a new
component-level action called 'displayNextBatch' and bind it to
that. This method does the requisite checks, and call the
displayNextBatch() method in display group if user is not editing.
Or as Josh Bloch would say "favor composition over inheritance".

class=MyDisplayGroup;
I got an error similar to my original one:
Error: com.webobjects.foundation.NSForwardException
[java.lang.IllegalArgumentException] While trying to set the field
"localizationCodesDG" on an object of type LocalizationCodePage we
expected a MyDisplayGroup but received a
com.webobjects.appserver.WODisplayGroup with a value of
sortOrdering=() qualifier=null localKeys=()

often happens if you forget to use a formatter.
Looks like you're using Java's default package. Maybe you need
to create a package for your custom classes and then specify the
fully-qualified class name as the error message does for
WODisplayGroup. Putting everything into custom packages is
probably a good idea even if it doesn't solve this problem.
If this fails, there may be a bug in the logic that creates a
WODisplayGroup that's in a WOComponent template. If you're intent
on using WODisplayGroup, maybe you should try removing it from the
WOComponent template and creating a MyDisplayGroup programmatically.
Aloha,
