You're welcome :) Sorry I thought you don't need keys. If you needed
them, then following would work:
public Map<String, List<MyObject>> getResult() {
return result;
}
<param name="includeProperties">
^result\.[^\[]+\[\d+\]\.interestingProperty$
</param>
Then only limitation of this one is that keys should not contain [
character because of [^\[]+ which I had to use instead of .* to avoid
including all of the model.
Kind Regards.
