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)

Exception in thread "main"

 

 

To fix this, change the JMDIDesktopPane class as follows:

 

public void addPropertyChangeListener(PropertyChangeListener listener) {

if(propertySupport != null)

propertySupport.addPropertyChangeListener(listener);

}
