Symptoms

Issue occurs when trying to apply conditional formatting on a column using a condition "column is NULL" in a UNION report.

Example and Steps to Reproduce:

1. Use  Bi Sample Apps
       New > analysis > A - Sample Sales
2. SELECT
        "A - Sample Sales"."Sales Person"."E8  Manager Number" s_1,
        "A - Sample Sales"."Sales Person"."E9  Manager Name" s_2,
        FROM "A - Sample Sales"
3. Add a filter  ("Time"."T00 Calendar Date" = date '2008-01-03')
4. This query will return one row with NULL values.
5. In criteria select  "E9  Manager Name" and go to column properties >conditional format
              Column= Column Column
              Operator= is NULL
              Pick a format (like a background color)
              OK
6. Go to results
7. The conditional format is not applied on the cell with a NULL value

Note: If you create an expression testing the values, the NULL value is verified.
   CASE WHEN "A - Sample Sales"."Sales Person"."E9  Manager Name" is NULL
THEN 'THis is NULL' ELSE "A - Sample Sales"."Sales Person"."E9  Manager Name"
END
