jasperreports 4.0.1 and 4.5.0 compatibility

[munga]

Is jasperreports suppose to be backward compatible, I have a report that works fine with 4.0.1 library but fails with a Class cast exception when using 4.5 library.

This kind of errors are usually generated by field misconfigurations: you probably have a Double field inside a TextField that says that its expression is of type Boolean. This has nothing to do with backward compatibility.

For anyone else who finds this, here is the link to bug report -http://jasperforge.org/plugins/mantis/view.php?id=5609

 

Occurs when there are non-unique conditional style names between the subreports.
