------------------------------------

             Summary: Change current view-link requirement to allow use of  
entity-condition only in view-entities
                 Key: OFBIZ-11179
                 URL: https://issues.apache.org/jira/browse/OFBIZ-11179
             Project: OFBiz
          Issue Type: Improvement
          Components: ALL COMPONENTS
    Affects Versions: Trunk
            Reporter: Leila Mekika


To explain the subject, i will give an example encountered recently:

We used, for a customer project, a view with Agreement, Virtual and Variant 
product entities and where the agreement can be attached to a virtual OR a 
variant product.
So to make a view returning Variant Product, Virtual Product AND Agreement 
informations, i could not create a view, as the key-map link is mandatory and 
made it impossible.

I can not have an alternative relation to the same entity so we have to 
duplicate member-entity and an alternative relation path (see attached file 
ExampleWithKeyMap.xml)
And as the coalesce is not an existing function, it require to update the 
framework. The result is a complicated and ugly entity-view

I think this can have been much simpler if i could have done it directly 
through the entity-condition (see the AGPA/PDTA view link in attached file 
ExampleWithoutKeyMap.xml)


So the purpose of this jira is to add the possibility to create a view-link 
without key map, only if there is an entity-condition.

You can test by applying the given patch and add the entity view from attached 
file ExampleWithoutKeyMap.xml
