I've had to look at higher priorities for a couple of days :)
Thanks for the idea. I changed as follows:
...
// private transient Log log =
LogFactory.getLog(ChartWizardForm.class);
private transient Log log; // Logging instance for this class
...
public ChartWizardForm() {
showInactive = false;
altClassMeasOrder = false;
...
outputFmt="";
scaleFactor="";
log = LogFactory.getLog(ChartWizardForm.class); // <-- ADDED
INITIALIZATION HERE
}
...
But, still get the NPE :(
I'm defininig the instance variable as transient because Tomcat
complains about saving sessions that contain a private instance variable
(non-transient) of type Log. I was trying to get my sessions to persist
across restarts. Does that suggest anything?
Thank you again - Richard
