Hi Trine and Jamie

1) This is correct and is also scheduled to be fixed.

2) I will strongly recommend against your proposal Jamie - do not edit 
the project file unless you really know what you are doing. Editing XML 
files is not an easy task and the risk is that you will end up with a 
broken file that you cannot use again. I have put Trine's suggestion on 
my todo-list, such that Auto-increment fields can be used in 
calculations as well.

3) Although Jamies suggestion is correct, this is only for Manager v. 
1.3 and up. This is not implemented in the current stable release 1.1.2, 
but hopefully we are ready to release the current pre-release versions 
as stable version within a short time.

Torsten B. Christiansen.

When you create the project in Manager, add the comparison (still will need =), but to any other field. Save the project and open it in a plain text editor. Find the line with the comparison. It will look like this
>         <Compare toFieldRef="V1" type="fcLT"/>
> Change the value for toFieldRef to the field name of your Auto Increment. This works as long as you do not edit the field again in Manager.
