Hi, I use a rest service from jasper studio. My data is for example : "5.65" (In JSON format) When i click on Data preview , it show only '5'. (The field is BigDecimal) In my web service, if i change the mysql query with REPLACE (myValue, '.',',') // Replace dot by comma[/code] The JSON become : '5,65' and it works ... How can i cast this value in Jasper to avoid the use of replace... Thanks
