One-to-many relation: ResultSet contains ... multiple times

[zb226]

Whenever an element class of an aggregate has its own field for the ID that is also used as keyColumn for the one-to-many relationship to its aggregate root, access to these elements will cause duplicated columns in the generated SQL and consequently warnings like:

ResultSet contains id multiple times

The problem is described in detail in this StackOverflow question.

Here is a small project repo to demonstrate the problem.

Desired behaviour: No warnings, the column accesses should probably be "squashed".

Hi,

Any news here?

How is it going now ?

@codering It looks like the patch provided by @schauder wasn't satisfactory for the spring-data project lead :(

The project lead was quite happy with it (that's me). But Mark wasn't satisfied and I failed to convince him or improve the PR. I'll try to revisit it next week.
