ppVariable calculations behavior changed from RB7 > RB10

rbuser

Hi,

Simple report
Detailband:
-TppVariable ppDummyVar Calculate On: Traversal Reset
On:ReportEnd

ppDummyVar.OnCalc:
ppSumField1Var.Value := ppSumField1Var.Value +
DetailBandPipeLine.GetFieldValue('Field1');
ppSumField2Var.Value := ppSumField2Var.Value +
DetailBandPipeLine.GetFieldValue('Field2');

Summaryband:
-TppVariable ppSumField1Var Calculate On: Traversal Reset
On:ReportEnd
-TppVariable ppSumField2Var Calculate On: Traversal Reset
On:ReportEnd

RB7: Correct tortals
RB10 Wrong totals: the first traversed record gets added twice!!!!!!!

We have 100+ reports doing this type of calculations

What's going on?

My guess is that the ppDummyVar.DataType is set to dtString. Try modifying
the DataType to be a numeric type such as dtInteger, dtDouble and then
re-test.

When set to dtString, the Variable.OnCalc will fire more frequently. This is
necessary to fix bugs reported by customers using the Variable to print
strings. When set to dtString, the Variable cannot cache intermediate
results, we had customers with complex subreport and KeepWithTogether cases
in which the simple String Variables showed the wrong value.

You are right. What a relief.

Thank you Nico
