Here is my implementation of data for testing (from Category.java):
public NSDictionary data() {
return new NSDictionary("key", "stringValue");
}
and my showFilter (from CategoryController.java):
public static ERXKeyFilter showFilter() {
ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.include(new ERXKey<NSDictionary<String,String>>("data"));
return filter;
}
results in:
"data":{"nil":true}
I assume this is the result of something incredibly obvious that I have
overlooked :-).
