I've tried this, but I always get an NPE when I have an own converter and the
"Select Color Popup" opens:
Caused by: java.lang.NullPointerException

My XHTML:
<tr:inputColor label="BGColor"
value="#{data['editItem'].headerBgColor}">
<tcc:colorStringConverter />
</tr:inputColor>
My Converter:
import java.awt.*;
import javax.faces.component.*;
import javax.faces.context.*;
import javax.faces.convert.*;
import org.apache.myfaces.trinidad.convert.*;
public class ColorStringConverter implements Converter {
private static final ColorConverter TR_CONVERTER = new ColorConverter();
public Object getAsObject(FacesContext context, UIComponent component,
String value) {
Color color = (Color) TR_CONVERTER.getAsObject(context,
component, value);
return getAsString(context, component, color);
}
public String getAsString(FacesContext context, UIComponent component,
Object value) {
return TR_CONVERTER.getAsString(context, component, value);
}
}
BTW, a bit of topic, but the "Select Color Popup" opens in a new browser
window. I have
<context-param>
<param-name>org.apache.myfaces.trinidad.ENABLE_LIGHTWEIGHT_DIALOGS</param-name>
<param-value>true</param-value>
</context-param>
in my web.xml.
Would be nice to see the popup use the lightweight dialogs framework at some
time in the future.
Best regards

have you tried a custom converter that internally uses the Trinidad
ColorConverter
but returns a String of the java.awt.Color ?
Like:
getAsObject(...)
{
...
Color c = ctrinidadColorConv.getAsObject(...);
return c.toString();
}
