Cannot cast from Float to String

[Ajenjo]

Hi.

 

I have a class with these atributtes.

 

Code:

/**
	 * Constructor for required fields
	 */
	public BaseAlbaranCuadernosLineas (
		java.lang.Integer id,
                com.siega.vo.Albarancuadernos idAlbarancuadernos,
		java.lang.String concepto,
		java.lang.Integer cantidad,
                java.lang.Float precio,
                java.lang.Float iva,
                java.lang.Float importe) {
(...)

 

As you see, I have type Integer, Float and String.

 

In the .jrxml are the following fields.

 

Code:

[code] (...) <field name="concepto" class="java.lang.String"/> <field name="cantidad" class="java.lang.Integer"/> <field name="precio" class="java.lang.Float"/> <field name="iva" class="java.lang.Float"/> <field name="importe" class="java.lang.Float"/> (...)

 

But when I compile the file, show the next error:

 

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. Cannot cast from Float to String value = (java.lang.String)(((java.lang.Float)field_iva.getValue()));//$JR_EXPR_ID=12$ <---------------------------------------------------------> 2. Cannot cast from Float to String

(...)

 

And when I change the types to String the error show that it´s not good value for the type.

 

Error evaluating expression :

Source text : $F{cantidad}

 

I can´t change the types because I have to do some operations with the values.

 

Any idea?

 

Thanks

I assume you have a text field that uses an expression like

Code:

<textFieldExpression>$F{iva}</textFieldExpression>

 

If this is the case, you will have to change it to

Code:

[code] <textFieldExpression class="java.lang.Float">$F{iva}</textFieldExpression>

 

If this is not the case, please post your entire JRXML so that we can see where the error comes from.
