How to repeat:
Unable to repeat. My second attempt to set the foreign key worked without the error being generated.

What exact data types referencing and referenced columns have?

Hi,

The datatypes are both INT. 

I have encountered the problem a few times now. It happens when I click  to open the drop down menu of foreign key choices. It seems to happen randomly, I can't pinpoint anything I am doing to make it happen! But when it does happen, if I click to a differnet tab and then back to the foreign key tab then it works fine.

I think if I click the drop down menu after the error then the list is empty. I will double check if I get the error again.

Does it happen with Referenced Table or Referenced Column drop down box?

It is the Referenced Column.

Many thanks for writing a bug report.

Unfortunately, we have too less informations here to make
a deeper analysis.

We either need to know how we can reproduce this or we
need a backtrace.
