Subreport Return value

2005-11-28 07:34

Hi all,

 

I still can't get my subreports to return a value to the master report. I keep getting null values.

 

Is there something special I have to put in the master variable expression to recieve the subreport value? Also, it throws errors when I try to use a custom subreport variable instead of using one of the built in variables.

 

Any help would would be great!

 

Thanks

try set the evalution time to band or group.

Alternatively, try setting evaluation time to auto in iReport 3.1.1 - I had tried band and group and neither of those worked - Auto seemed to fix the null issue.

Hi,

I am having the same problem.

I want to know how many rows a subreport printed, so I can put in my master report "No data found" when this would be 0.

So in my MASTER i have a variable "TOTAL_TELECOM" :

    Calculation type: System

    Reset & Increment Type: None

I define a return value when including the subreport :

    Subreport variable = REPORT_COUNT

    Destionation variable = TOTAL_TELECOM

    Calculation Type: Nothing

I want to print the TOTAL_TELECOM variable in a text field :

    $V{TEL_COUNT} with Evaluation Time: Auto

 

So far I gathered from reading here and there.

Still, I'm printing nulls :-(

Any ideas ?

 

Thanks on beforehand !

Sven.

Found an easy workaround :

Not an active forum here I'd say.

This is the 2nd time I've solved my own problem before anyone replied.
