A Bug in SqlDateConverter?
Now I use wicket 1.3.5. There is a date field in my webpage.and it is not required. The date class type is java.sql.date But I alway have a NullPointerException while the input of this optional field is empty. the exceptions below: Caused by: java.lang.NullPointerException at org.apache.wicket.util.convert.converters.SqlDateConverter.convertToObject(SqlDateConverter.java:35) at org.apache.wicket.markup.html.form.FormComponent.convertInput(FormComponent.java:1211) ... How do I fix this problem? Now I must set a date into my date filed to pass the program.But this field is not required.

Re: A Bug in SqlDateConverter?
I recommend porting to 1.4-rc2 already ;)
Alternatively you can override / patch the SqlDateConverter with a new class:
package org.apache.wicket.util.convert.converters;
public class SqlDateConverter extends AbstractConverter
{
private static final long serialVersionUID = 1L;
/**
* @see
org.apache.wicket.util.convert.IConverter#convertToObject(java.lang.String,Locale)
*/
public Date convertToObject(final String value, Locale locale)
{
if (value == null || Strings.isEmpty(value))
{
return null;
}
else
{
return new Date(((java.util.Date)parse(getDateFormat(locale),
value, locale)).getTime());
}
}
/**
* @see
org.apache.wicket.util.convert.converters.DateConverter#convertToObject(java.lang.String,
* java.util.Locale)
*/
@Override
public String convertToString(Object value, Locale locale)
{
final DateFormat dateFormat = getDateFormat(locale);
if (dateFormat != null)
{
return dateFormat.format(value);
}
return value.toString();
}
/**
* @param locale
* @return Returns the date format.
*/
public DateFormat getDateFormat(Locale locale)
{
if (locale == null)
{
locale = Locale.getDefault();
}
return DateFormat.getDateInstance(DateFormat.SHORT, locale);
}
@Override
protected ClassDate getTargetType()
{
return Date.class;
}
}

Re: A Bug in SqlDateConverter?
Note, that the SqlDateConverter -class must use java.sql.Date when it returns the value. (that's why it is called 'SqlDateConverter') ** Martin 2009/2/22 Martin Makundi martin.maku...@koodaripalvelut.com: In my opinnion yes. Try the snipplet I sent you.

Re: A Bug in SqlDateConverter?
Here you are. html and java files are both uploaded as attachments for your reference. Data type of the date field in my entity is also java.sql.Date. By the way,instead of above method, Now I have a try to change all the date type of Date from java.sql.Date into java.util.Date. Then everything is fine. -- If input is null and the field is not required converters do not run.

Re: A Bug in SqlDateConverter?
igor, I'm not sure if the datepickers removed will make the error go away. Since all of my programs have been refactorred from java.sql.Date to java.util.Date,I can't try your assumption in my application now. Anyway,now I adopt java.util.Date instead of java.sql.Date,and everything goes well. Thanks. roland. -- does the error go away if you do not add the datepickers? -igor -- View this message in context: http://www.nabble.com/A-Bug-in-SqlDateConverter--tp22145097p22156014.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
