It doesn't work.

Hi I call a java class's function in my report, but when the function's parameter is BigDecimal and the value is null, the report won't call this function and the field will display null. for example: If there is a function in a java class, and a report will call this function : public static String getNumber(BigDecimal number){ return "number: "+ number; } if the numbe's value is null, the report won't execute this function when exporting report. is it a bug? This problem happens when I upgrade jasperreport from 3.7.0 to 4.0. and I found a similar issue by another report: http://jasperforge.org/projects/jasperreports/tracker/view.php?id=5138 Post Edited by lance at 03/23/2011 01:49

I want to change the report element's position dynamically according to the parameters. Can jasperreport do that? thank you!

How to delete a record in JRDatasource? thanks!

you need to set the evaluation time in properties

When I use conditional style in jasperreport, and the conditional expression contains a variable which is the sum of a field. when I use the style in a group header, the conditional style does not work because the variable is not correctly calculated. I also can't set the variable's evaluation time in the conditional style. and I also find the same problem in the print whe expression. can someone know how to solve this problem, thanks!
