 CURRENTLY DOING: more misc stuff below to complete workorder!!!
 
-create a view "viewaworkorder" which includes age calculated as interval and aliased as "expage"
-change all workorder lists to use a view as the top workorder level and add the expage column as done in test version
+X create a view "viewaworkorder" which includes age calculated as interval and aliased as "expage"
+X change all workorder lists to use a view as the top workorder level and add the expage column as done in test version
 implement interval / duration filter for use in grids, definitely can support greater than / less than and between
 equals is probably useless so don't implement at all
-implement at the back end as criteriabuilder for intervals (type 16)
+implement at the back end as criteriabuilder for intervals (type 15)
 done when can filter and view workorder* lists by age / duration
+select serial,createddate, expwoage from viewaworkorder
