[jira] [Comment Edited] (OFBIZ-12037) Bug in seed data for UomType / Uom

How would we handle erasing "WEIGHT_MEASURE"? 

 

If we erase the "weight measure" type and the related Uom's from the seed data, and someone already wrote a ofbiz application that did a "where UomType = 'WEIGHT_MEASURE'" kind of thing, it would break that for them when they went to set up their new installation.

 

We could tell those people who were upgrading to use the new seed data, but then  they would still have the old data laying around.

 

What's the expected way to handle something like this?

> I found a problem in the seed data.  The kilogram, is under the wrong measure type.  The kilogram is a unit of mass, not a unit of weight. 
> Explanation: The weight of a product/object changes with altitude, the mass does not.  (example: If you want to lower your mass, then you need to diet, but if you just want to weigh less, then just live on mars.)
> (These are easy to confuse because of a naming collision:  there is a unit of mass called the pound and also unit of force called the pound)
> Basically, we should change:
> <UomType description="Weight" hasTable="N" uomTypeId="WEIGHT_MEASURE"/>
>  To be:
>  <UomType description="Mass" hasTable="N" uomTypeId="MASS_MEASURE"/>
>  <UomType description="Force" hasTable="N" uomTypeId="FORCE_MEASURE"/>
>  
> With seperate Uoms under each UomType
