I recently submitted a broader (and probably confusing) post on table inheritance. I now have a better worded post (in my opinion) on a more specific subject.

Scenario:

1. TableA is abstract with a ForeignKey relation to TableFK.

2. TableB is a descendant of TableA

3. Add TableB and TableFK to a form.

4. On dataSource TableB set Join Source to TableFK and Link Type to Delayed

The result I get: No link at all.

I ended up linking them by code.

Could someone test if they get the same result please. It would be much appreciated.

If it is not only in my case, does it count as a bug? It seems reasonable that it should work as normal

I recently created another table inheritance structure. And I got the same result. And on a related topic. Using this functionality is very slow. I first blamed the server I was using. But I sold my soul for a Mac Pro - 6 cores 64GB RAM. On it I run a VM which I assigned 40GB of RAM and 4 cores. I should say that is enough resources. And under those circumstances it still takes around 5 seconds to create a new field in a table that supports inheritance and around 10 seconds to add a table that supports inheritance to a form.
