Log:
Improved: Change current view-link requirement to allow use of  
entity-condition only in view-entities
(OFBIZ-11179)



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.
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 is to add the possibility to create a view-link without key map,  
if there is an entity-condition.

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

Thanks: Leila Mekika
