Arraybuild error in v.b40

After updating to 10.2.0.b40,

arraybuild is giving the error fieldvalue( function: data field “SELFR_IN” does not exist.. Also get the same error in the relational workshop when i use the drop down to add the field to the formula.

Running the file in b38 works as expected.

I cannot duplicate this problem. I created a database with a field named SELFR_IN and it worked just fine in the arraybuild( function and when using the Relational Workshop.

Perhaps you could provide some additional information as to how you got to this error.
