More data:


This gives partial results:

<dtml-in "Catalog(process_step=['start','mailed'],
sort_on='subject_name')">

This gives full results:

<dtml-in "Catalog(process_step=['start','mailed'],
sort_on='subject_name')[:]">

This gives full results:

<dtml-in "Catalog(process_step=['start','mailed'],
sort_on='subject_name')" sort="subject_name">
