using variables with group as reset type
2003-01-28 06:28
Receiving an error when trying to use the system generated count variable for my group. The group the xml file is showing the group has been created, but the compiler is throwing an error. Below is the error, the xml code for the group, and the java code used to create the group. Any help appreciated.
Thanks

Jessica

Hi,

This is where you got it wrong:

//create group
groups = design.getGroupsList();
groups.add(0, group);

You have to use the
JasperDesign.addGroup(JRDesignGroup)
method to add groups.
Adding them to a list that to previously get from
the report design object has no effect.

I hope this helps.
Teodor
