[JR1.3.3] ClassCastException:JRBaseLine


Recommended Posts



I just downloaded JR 1.3.3 and tried the demo under jasper, but the problem shows:


ant viewDesign:



[java] class net.sf.jasperreports.engine.base.JRBaseElementGroup

[java] Exception in thread "main" java.lang.ClassCastException: net.sf.jasperreports.engine.base.JRBaseLine

[java] class net.sf.jasperreports.engine.base.JRBaseLine

[java] at net.sf.jasperreports.view.JasperDesignViewer.main(JasperDesignViewer.java:311)


I checked the code and docs, looks like the JRDesignElement Class just a subclass of JRBaseElement, the element JRBaseLine OR JRBaseElement can not be casted to JRDesignElement.


After I tried to use the 1.3.2.jar, it turned to be OK.


Does anyone had the same problem?


Is this a bug or something else?
