What's wrong?1. Cannot cast from boolean to Object value = (java.lang.Object)(((java.lang.String)field_Turbina.getValue()).equals("VO"));//$JR_EXPR_ID=9$

[andy_ratiu91]

I have to do a total count of the values equal to "VO" from a column. I created a variable named: CountV,  class type: java.lang.String, calculation type: Count, expression: $F{Volumetric}.equals("VO").

When i execute it shows: 

Cannot cast from boolean to Object value = (java.lang.Object)(((java.lang.String)field_Turbina.getValue()).equals("VO"));//$JR_EXPR_ID=9$

 

Please help me...i started using IReport for a couple of days and i struggle here...

Hi,

Create a variable, with a "sum" increment function, with datatype Integer. Then, enter "0" as initialization value, choose the right reset and increment triggers and use the following expression as a variable expression :

 $F{Volumetric}.equals("VO")?1:0

And tell us if it works.

Cannot cast from int to Integer value = (java.lang.Integer)(((java.lang.String)field_Volumetric.getValue()).equals("VO")?1:0);//$JR_EXPR_ID=11$  

Cannot cast from int to Integer  value = (java.lang.Integer)(0);//$JR_EXPR_ID=12$

 

----these are the errors shown...

As found here :  http://community.jaspersoft.com/questions/525053/cannot-cast-int-integer

coud you try : new Integer($F{Volumetric}.equals("VO")?1:0 )
