Christian Carlow updated OFBIZ-6427:
------------------------------------
Attachment: OFBIZ-6427_poc.patch
This patch is still a work in process and provided as a proof of concept. As
of right now the grouping functionality is only supported for TextFindFields
and needs to be extended to the other find fields including drop downs which
are the only find type field that may not be used as find so the xsd should
probably be extended to indicate when a dropdown should be used as a find field
or not.
The patch adds the multi sort functionality of OFBIZ-6428 upon which the
grouping is dependent. OFBIZ-6428 may be patched separately and extracted from
this patch.
> Implement FindService record grouping/summarization functionality

> Just as sortSeq and sortDir will be added to find fields like ignoreCase is
> available, groupBy check box would also enhance user query capabilities.
> FindService would have to be extended to process the list and create
> group/summary records.
> For example, if a grid/form lists customer orders and the user wants to
> determine the total quantity and price of products ordered between a date
> range, then check marking the groupBy for productId would insert a grouping
> record before the details containing totals.
> This issue is primarily meant to handle reports for which pagination isn't
> used because all records are displayed. For these reports queries, group
> totals can simply be calculated by looping each detail record. But if
> pagination is used, the method of calculating totals for grouping records
> becomes more complicated because if detail records exist outside of the
> current page but are part of a group being summarized then they will be
> excluded from the group total unless implemented some other way.
