WB allows users to define two different numeric columns as auto-increment, incorrectly.  The resulting DDL cannot be applied.

How to repeat:
Create a table with two INT columns, check AI for both.

Suggested fix:
Only allow one AI per table.

I think this is not a bug at the moment.

Validation check only is included in Workbench SE.

Checking AI on two columns should work in SE.

My guess here is that you tested OSS and not SE.

Is my guess right?

Many thanks for writing a bug report.

There is no validation check here in life editor for more then single auto_inc.

Changed so that previously set auto-inc columns are unset if a new one is toggled.

An entry has been added to the 5.2.21 changelog:

MySQL Workbench allowed setting the auto-increment checkbox for multiple columns in the Table Editor.
