Error on iReports startup

2004-02-14 14:20

I'm getting the following error:

 

 

java.lang.NullPointerException

at it.businesslogic.ireport.gui.JMDIDesktopPane.addPropertyChangeListener(JMDIDesktopPane.java:91)

at javax.swing.plaf.basic.BasicDesktopPaneUI.installListeners(BasicDesktopPaneUI.java:134)

at javax.swing.plaf.basic.BasicDesktopPaneUI.installUI(BasicDesktopPaneUI.java:101)

at it.businesslogic.ireport.gui.MainFrame.<init>(MainFrame.java:84)

at it.businesslogic.ireport.gui.MainFrame.main(MainFrame.java:4122)

Exception in thread "main"

 

 

To fix this, change the JMDIDesktopPane class as follows:

 

public void addPropertyChangeListener(PropertyChangeListener listener) {

if(propertySupport != null)

propertySupport.addPropertyChangeListener(listener);

}
