Hi,
I´m in trouble with NSTimestamp. I´m using this to store the durrent
date to a database. While there is no need to edit this date I´ve
altered the acceorclass for the database object like that:
public void setBriefDatum()
NSTimeStamp value = new NSTimeStamp();
takeStoredValueForKey(value, "briefDatum");
}
When you hit the new button in my form a new object "briefe" is
initialisied ,which includes the datafield "briefDatum", I then call the
"setBriefDatum" method and the date shows up in the connected Formfield.
You can enter your data and hit the save button. After that an exception
occured. Funny thing, it occures when all my code is finished and the
page is displayed again. Data is saved to database, all aftersave work
of my code is executed, don´t know where error might be.
The error message:
[2006-08-30 13:20:18 CEST] <WorkerThread6>
<com.webobjects.appserver._private.WOComponentRequestHandler>: Exception
occurred while handling request:
java.lang.ClassCastException
