I followed the tips of counting the groups with the following code:

 

<variable name="GroupCount" class="java.lang.Integer" resetType="Group" resetGroup="MyGroup" calculation="System">

<variableExpression/>

<initialValueExpression>

($V{GroupCount} != null) ? (new Integer($V{GroupCount}.intValue() + 1)) : (new Integer(1))

</initialValueExpression>

</variable>

 

I found that if I have multiple groups, the GroupCount does not reset. It just keep growing.

Does anyone experience the same problem? Is it a bug?

Hi,

 

This is just a trick which is useful

in simple reports.

Is true that when having nested groups

the variable is not reinitialized when

a parent groups breaks.

 

But a complete control over such a counting

variable you have if you use scriptlets.

There you can increment and reset the variable

as you want.

 

Good luck!
