Hello,

I have the following problem with dateChooser. I have element

<ig:dateChooser value="#{iterationController.iteration.plannedEffectivityStart}" converter="shortDateConverter"></ig:dateChooser>

where I use "converter" attribute. I have defined and implemented converter. First definition in faces-config.xml:

<converter-id>shortDateConverter</converter-id>

<converter-class>com.anect.rmt.web.converters.ShortDateConverter</converter-class>

</converter>

ShortDateConverter implements Converter interface:

public class ShortDateConverter implements Converter {

public Object getAsObject(FacesContext context, UIComponent comp, String date) {

...

}

public String getAsString(FacesContext context, UIComponent comp, Object date) {

...

}

When I want render the page, I see exception:

java.lang.IllegalArgumentException: argument type mismatchat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Converter implementation:

import java.text.DateFormat;

import java.text.ParseException;

import java.util.Date;
import java.util.Locale;

import javax.faces.component.UIComponent;

import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import org.apache.commons.lang.StringUtils;
public class ShortDateConverter implements Converter {

public Object getAsObject(FacesContext context, UIComponent comp, String date) {
if (StringUtils.isEmpty(date)) {
return null;
}

try {
Locale l = FacesContext.getCurrentInstance().getViewRoot().getLocale();
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, l);
return (Object) df.parse(date);
} catch (ParseException e) {return null;
}

}

public String getAsString(FacesContext context, UIComponent comp, Object date) {if (date == null) {return StringUtils.EMPTY;
}

if (!(date instanceof Date)) {return StringUtils.EMPTY;
}

Locale l = FacesContext.getCurrentInstance().getViewRoot().getLocale();
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, l);return df.format(date);
}

}

I think, it is clear, I don't see there any possible problem. Only easy converter, that converts data for dateChooser and back. Do you want see whole stack trace? Thanks.
