insertInto() with returning() creating new row but not returning value

[Ian Clarke]

I'm trying to use the following code to create a row in my "campaigns" 
table: https://gist.github.com/f3f7580dcca4f9d28ae8 (using Jooq with Mysql).

The campaign is created in the DB, but campaignRecord is null after this 
statement, whereas I would hope it would contain the generated value for 
the "id" field (which is set to autoincrement in my schema).

What am I doing wrong here?

Ian.
