Problem with <variableExpression>

2003-10-29 12:47

I have a variable and I want to increment it if the field, which is called "PaymentMethod", is equal to "PAC".

 

<field name="PaymentMethod" class="java.lang.String"/>

......................

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

<variableExpression>($F{PaymentMethod}.equals("PAC"))?(new Integer($V{numPACContracts}.intValue() + 1)):($V{numPACContracts})</variableExpression>

<initialValueExpression>new Integer(0)</initialValueExpression>

</variable>

 

However, numPACContracts is always 0. I am pretty sure there is "PAC" in the datasource, so it shouldn't be the datasource's problem.

 

Anyone have any idea why it is always the initial value?

 

I also have tried ($F{PaymentMethod}=="PAC"), but still doesn't work

 

Thank you
