I'm running MDG 7 and have created a custom model with 3 entity types - all type 1 with one to many cardinality.
The idea being that the first entity type allows basic data of a material to be populated, which can then be used as a template in multiple materials with more detail. Which in turn can be used as a template for multiple full blown materials.
I'm having trouble with adding more than one entity type into my UI configuration. I seem to only be able to add one entity type to each UI block.
I'm using the proxy feeder class.
How can I ensure that fields from all three entity types can be used in my UIBB?
Thanks in advance.
