------------------------------------------------------------------
With regard to identification of fields that should be calculated/summed of
last message, I'll likely keep it simple for now and implement as an
enhancement to form widgets. An additional functionality should probably be
provided to allow for users to choose different summarizations such as sum,
avg, min, max, etc.

> Project: OFBiz
> Issue Type: Improvement
> Components: framework
> Affects Versions: Trunk
> Reporter: Christian Carlow
>
> 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.
