- Combined template fields process an input column even though their input comes from the combiner. This means that all combination fields have to be at the end of the fields list or input will be skipped. The exception to this seems to be if a table field is listed twice, in which case it will not skip even if you'd like it to.
- I can't choose to skip irrelevant input columns, because all template fields have to map to a table field. I'd like to be able to select a "none" table field value, or similar.
- When combining two columns they have to map to table fields before being combined. This doesn't work in all cases and I had problems combining address fields for the contact_details table.
- Another issue with input columns needing to map to table fields is defining static table field values which don't correlate to an input column. I suppose they have to go at the end of the fields list.
- I'm having problems setting a unique alias. A plugin to generate a line number could be one way of doing it
I hope that's helpful. Please let me know if I've missed how to do any/all of these.
