Set default value rather blank.

[sulaiman2043]

I am having two issues in jasper report.

 

1- i am using an if condition to set a value of a text field if null found for e.g. $F{RATE}.equals(null) ? new BigDecimal(0.0000) : $F{RATE}. and when i run the report it show blank rather showing 0.0000. Is it like this to set the value or is there anyother way around to set the value.

 

2- when i set the textfieldExpression to set the data type it doesn't set it. when i manually define in xml then it is working fine. but after that if i move any text field or any change any element in reoprt that dataype just been removed automatically. Is it a bug in ireport or what?

 

I am just stuck into these problems.

Are you sure you have this line correct?

$F{RATE}.equals(null) ? new BigDecimal(0.0000) : $F{RATE}

I'm thinking that the above statement would cause a null pointer exception if RATE is null.

Typically I've always defined it as

$F{RATE} == null ? new BigDecimal(0.0000) : $F{RATE}

Another way which is the suggested by "Effective Java 2nd Ed." would be:

$F{RATE} == null ? java.math.BigDecimal.valueOf(0.0000) : $F{RATE}

I've done that quite a bit before and had no issues.  I haven't seen any issues defining data types using IReport.  Seems unusual you can't define a data type there.  Did you try changing focus from the data type UI element before trying to save your report?

I have also tried with this

$F{RATE} == null ? new BigDecimal(0.0000) : $F{RATE}

and this $F{RATE} == null ? java.math.BigDecimal.valueOf(0.0000) : $F{RATE} but still no change...I also think there should be not an issue with this but still i am stuck into this.

Is it possible for you to boil down the most limited .jrxml possible and attach it?
