Error when creating conditional calculation in 8.4.1

[RistaF]

Hi

We have just upgraded from 8.4 to 8.4.1 and now reports that have conditional calculations, and are based on joined queries, are failing with the following error:

QE-DEF-0359 The query contains a reference to at least one object '[object]' that does not exist.QE-DEF-0030 Expression parsing error.QE-DEF-0359 The query contains a reference to at least one object '[object]' that does not exist.QE-DEF-0030 Expression parsing error.QE-DEF-0359 The query contains a reference to at least one object '[object]' that does not exist.QE-DEF-0030 Expression parsing error.

The error message lists all the items in the underlying queries.  I have specified values in the "properties" property, but is still getting the error.

When I replace the conditional calculation with  a straightforard aggregation, the report works.

Has anyone come across this before?

Regards
