how to conditionally display a field value?

[dprogrammer]

I want to display a field value conditionally. I have created a variable and I am using this syntax in 'TextFieldExpression':

 

$F{qtr}=="Q1" ? $F{Salary}.doubleValue():0

 

I am getting error "Can not cast from double to double".

Are you sure that's the exact error?

 

I've seen myself "Can not cast from double to Double"

or viceversa. For some reason Double and double, int and Integer cause those kind of errors.

 

Anyway is either the field or the variable that have a non- matching data type.

Here is the error:

1.ÂCannotÂcastÂfromÂdoubleÂtoÂDouble valueÂ=Â(java.lang.Double)(((java.lang.String)field_qtr.getValue())=="Q1"?((java.lang.Double)field_Salary.getValue()).doubleValue():0.0);

 

The variable and field both are of type double.

the FIELD is Double, so put a "new Double()" around the whole sentence and it will work.

If you just dont want to DISPLAY something,use the "print when expression" in "common" of any field.

The double Double difference is what I meant in my first post. JulEgner's answer will work, at least it works for me.

[dprogrammer]

It worked when I enlcosed the whole expression with new Double(). Is this a better solution or we can play around with a field's properties and achieve same without using a variable? My goal is to display a field value if it has a value that falls in any quarter and display 0 if no value for any quarter.

The layout of the report is as follows:

Quarter1 Quarter2 Quarter3 Quarter4

234.00 0.00 1234.56 34.00

 

Is is possible to do it without using a variable?
