Hi all. I'm using an arrayList which contains in each position a HashMap with the keys,and the values. when i'm compiling the error is: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. JRBeanCollectionDataSource cannot be resolved to a type value = (net.sf.jasperreports.engine.JRDataSource)(new JRBeanCollectionDataSource(((java.util.Collection)field_datosListado.getValue()))); //$JR_EXPR_ID=26$ <------------------------> 2. JRBeanCollectionDataSource cannot be resolved to a type value = (net.sf.jasperreports.engine.JRDataSource)(new JRBeanCollectionDataSource(((java.util.Collection)field_datosListado.getOldValue()))); //$JR_EXPR_ID=26$ <------------------------> 3. JRBeanCollectionDataSource cannot be resolved to a type value = (net.sf.jasperreports.engine.JRDataSource)(new JRBeanCollectionDataSource(((java.util.Collection)field_datosListado.getValue()))); //$JR_EXPR_ID=26$ <------------------------> 3 errors In the Data Source Expression propertie in the subreport i have this: new JRBeanCollectionDataSource($F{datosListado}) where datosListado is the field of the master report which have the arrayList.I have tried with field class like Collection,list and object and the error is the same. I don't know what to do. Thank you very much Post Edited by blackadder at 04/23/2009 09:13 Post Edited by blackadder at 04/23/2009 09:14

Hello. First of all,please forgive my bad english, i'm not very good whit it. I'm a newbie whit Ireport and i have some questios that i like to ask.The easiest first. 1º) I have to print one rectangle in the background of the records to make the odd records look direferent.How can i do do to print one record yes and one no the rectangle in the background. 2º) I have the total fields in the column footer of the report,but if i don't have enough records to fill a page,these fields stay at the bottom of the page and i want to fill whit blank records the gape between the records and the column footer. 3º) i have all the data en a map that i passed like recordset,but i have the record data (the part that i want to show in the detail) inside of an array list and i don't know how to show the records(maybe in a subreport ????) the recordset estructure: •image – java.io.file •name – java.lang.String •account – java.lang.String •prize – java.math.BigDecimal •season – java.lang.String •dataList – java.util.ArrayList. In each position of this Array there is a Map whit the following keys: o date – java.util.Date o import - java.math.BigDecimal o sales - java.math.BigDecimal o incomes - java.math.BigDecimal o exports - java.lang.String o shape - java.math.BigDecimal •Charge – java.lang.String •dni – java.lang.String •responsability – java.lang.String thank you very much and best regards
