Hi
Thanks for that.
I was actually trying to see if there was a way to ensure that eo's on their
own or as part of a relationship get returned in the same form by having
standard filters for each type of eo.
include(String keyName, ERXKeyFilter existingFilter) is exactly what I was
looking for.
So for my transaction filter with its to 1 organisation I can do:
ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.include("organisation", organisationFilter());
Where organisationFilter() is a filter determining how organisations should be
filtered.
Thanks
