Same me.Anyone can help?
Problem with sum of variables from 2 subreport
in Products
Posted
Hello,
I have a main report and inside two different subreports.
From each of the subreport I send back to the parent report a "returning value" (numerical value defined as java.lang.Double.
Imagine $V{value_1} is the formula for the value returned from the first subreport and $V{value_2} is the formula for the value returned from the second subreport.
They are processed and passed back fine, infact if I insert $V{value_1} and $V{value_2} in the main report, they show correctly.
My problem is now that I need to define a formula in the main report to make the sum of the 2 values.
I created a variable, $V{totalvalue}, defined as java.lang.Double; the formula is: $V{value_1} + $V{value_2}
If I insert it in the main report $V{totalvalue}, it display always "null".
It is probably due to an issue with the "time of evaluation" but I'm not able to figure out the correct settings I have to use.
Can someone help me?
