                 Key: OFBIZ-1134
                 URL: https://issues.apache.org/jira/browse/OFBIZ-1134
             Project: OFBiz
          Issue Type: Bug
          Components: order
    Affects Versions: SVN trunk
            Reporter: Iain Fogg
             Fix For: SVN trunk


Prelude:

To easily observe this problem, you need to modify a form definition. In 
applications/order/webapp/ordermgr/requirement/RequirementForms.xml to allow 
the facilityId field to accept an empty value by changing <drop-down 
allow-empty="true">.

Assumption:

+ Your list of approved requirements include some with and without a value for 
facilityId.

Scenario:

+ In the OrderMgr application, go to the "Requirements" screen and select 
"Approved Product Requirements".

+ By default, the Supplier field will be empty, and the form displays all 
requirements for all suppliers, irrespective of facilityId.

+ Select a Supplier (preferrably one with some requirements with a facilityId 
and some without), leave the facilityId empty, do the lookup, and the result is 
an empty list. Select a valid facilityId, do the lookup, and it returns the 
list of requirements for than supplier that have the relevant facilityId.

+ Clear the facilityId AND the Supplier, do the lookup, and you get the full 
list of approved requirements.

For some reason, the application correctly interprets an empty facilityId as 
DON'T CARE when there Supplier is empty, but is doing something else when a 
Supplier is selected.

Note: I observe this problem because I am testing on a snapshot of a production 
database that include requirements that may or may not have the facilityId 
field populated. In fact, the reason I have lots of requirements without a 
facilityId is because these are being generated by the Requirement Method Enum 
related secas. (Not sure if that is important but thought I'd mention it).
