variable sum calculation problem

2006-06-20 15:14



I have a report that consists of large number of subreports.

They are organized in pairs, where each subreport returns value in variable, for example:



(this is a one pair)

In that report I present

values like this: Double($V{q1Stop}.doubleValue() - $V{q1Start}.doubleValue())

in each iteration.

So far, everything works fine

but if I set another variable,

that works as a sum calculation of

expression based on variables returned from subreport

(sum of expressions: new Double($V{q1Stop}.doubleValue() - $V{q1Start}.doubleValue()) )

it does not always work

(in some cases it is set to null)

It almost looks like this variable is updated for band iteration before variables q1start and q1stop are set.


What am I doing wrong

and how to prevent it ?


thanks in advance,
