Hi Johan, I tried this
TextField dateFrom = new TextField("dateFrom",new
PropertyModel(filtr,"dateFrom")) {
public IConverter getConverter() {
return new IConverter() {
public Object convert(Object value, Class c) {
try
{
if(c == String.class)
{
return new
SimpleDateFormat("dd-MM-yyyy").format((Date)value);
}
else
return new
SimpleDateFormat("dd-MM-yyyy").parse((String)value);
}
catch(ParseException pex)
{
return null;
}
}
public Locale getLocale() {
return getLocale();
}
public void setLocale(Locale locale) {
}
};
}};
filtr is instance of class where is property
Date dateFrom with apropriate getter and setter. I always get this exception
when I try fill and post the field.
icketMessage: unable to set object 11.05.2000, model:
Model:classname=[wicket.model.PropertyModel]:attached=true:[EMAIL

Root cause:

DateTextField is unusable for me, becouse I'am planning to have more
acceptable format for my date -
dd.MM.yyyy and dd.MM.yyyy hh:mm , maybe you can consider this to be
useful for next releases of wicket :-)
Thanks for help.
