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.
