I've create a custom converter. When I submit an invalid value, the invalid.fieldvalue message is pop so I think my converter is working. But when i submit a null or whitespace, i got this "ognl.NoConversionPossible" message back into my textfield box. Why it dont use the same invalid.fieldvalue message. What is the "ognl.NoConversionPossible" ?
