Sub Report Return Values (iReport v3.7.3)

[griley]

I am attempting to return a value to the master report from a sub report.

I have set up a variable to contain the return value on the master report :

<variable name="OnCharge" class="java.lang.String" resetType="None"/>

I have also added a variable to the sub report :

<variable name="OnCharge" class="java.lang.String">
  <variableExpression><![CDATA[$F{ON_CHARGE}.toString()]]></variableExpression>
  <initialValueExpression><![CDATA[$F{ON_CHARGE}.toString()]]></initialValueExpression>
 </variable>

I have mapped the return value in the master report as:

<returnValue subreportVariable="OnCharge" toVariable="OnCharge"/>

 

However, the return value is always NULL even though the Field ON_CHARGE has a value.

Could someone please tell me where I am going wrong

 

Thanks

Are they set as System variables?

Check the Properties panel for the variable in the master report. Its Calculation should be set to System.
