Adding an object to a table, and setting it to editable

Vaadin 6 / 7 / 8 Framework Data Binding

I add an object to my table and when I make the table editable I get the following error:

“Unable to convert value of type com.tds.team.partmaster.FieldOptionObj to presentation type class java.lang.String. No converter is set and the types are not compatible.”

What do i need to do in the FieldOptionObj class to let it be editable? All I need is it’s string value to be editable.

Great thanks, I’ll try that.

For anyone wondering what my class looked like here it is. Slightly different than the example because I needed to keep a primary key along with the object.

public class StringFieldConverter implements Converter<String, FieldOptionObj>
{
    FieldOptionObj newFoptObj;
    public StringFieldConverter(int optionpk, String displayStr)
    {
        newFoptObj = new FieldOptionObj(optionpk, displayStr);
        
    }
    
    public FieldOptionObj convertToModel(String text,Class<? extends FieldOptionObj> targetType, Locale locale)
        throws ConversionException
        {
            if(text == null)
            {
                return null;
            }
            newFoptObj.setDisplayStr(text);
            return newFoptObj;
        }
    
        

    
    
    public String convertToPresentation(FieldOptionObj foptObj,
            Class<? extends String> targetType, Locale locale)
        throws ConversionException
        {
            if(foptObj == null)
            {
                return null;
            }
            
            return foptObj.getDisplayStr();
        }
    
        
    public Class<FieldOptionObj> getModelType()
    {
        return FieldOptionObj.class;
    }
    
    public Class<String> getPresentationType()
    {
        return String.class;
    }    
    
}
