Good day.

I'm pretty new to JSF so maybe the question is obvious But I've
googled for 3 hours and found no solution.

I'm developing proto JSF application with JPA (as the point of
integration I'm using Spring managed beans in the JSF context).

There is a need to create the input for JPA object which references
the another. I've created the following  converter:

public class SprPolConverter implements Converter {

    private ISprPolDAO getDao(FacesContext context) {
        return (ISprPolDAO) FacesContextUtils.getWebApplicationContext
(context).getBean("sprPolDAO");
    }

    @Override
    public Object getAsObject(FacesContext arg0, UIComponent arg1,
String id) {
        if (id == null )
            return null;

        Long _id = new Long(id);
        return getDao(arg0).getById(_id);
    }

    @Override
    public String getAsString(FacesContext arg0, UIComponent arg1,
Object obj) {
        if (obj == null )
            return null;

        return "" + ((SprPol )obj).getId();
    }

and registered it as the  default converter for type
    <converter>
        <converter-for-class>com.uniqa.persistence.spr.common.SprPol</
converter-for-class>
        <converter-
class>com.uniqa.ui.converters.spr.common.SprPolConverter</converter-
class>
    </converter>

It's used anytime I submit the form - and returns the correct values
(looking in the logs - everything returned from converter is fine).

But I always receive the Validation error: Value is not valid....

any idea?
