oops, strange....
there is an additional getter on a variable, that causes this error:
private java.util.Date gebdat;
public String getGebdatStr() {
// don't work: return gebdat.toString();
return "Hello World!"; // this ist Ok! ????
}
If if "gebdat" is null, then calling getGebdatStr as written will
throw a NullPointerException; that's probably what you're seeing
here. The JavaBeans spec doesn't allow for properties to be null,
anyway, although Jess doesn't care about that. Your properties should
have valid default values.
