Leonardo Uribe commented on MYFACES-1891:
-----------------------------------------
The problem described before is a variant of the original exception.
The solution is a little bit different from the proposed on the modified
RendererUtils file (but the file helps to find what's wrong, thanks Patrick for
the patch). It is add this code to getConvertedStringValue (look the last
return):
public static String getConvertedStringValue(FacesContext context,
UIComponent component,
Converter converter, Object value) {
if (converter == null) {
if (value == null) {
return "";
}
else if (value instanceof String) {
return (String) value;
} else if (RendererUtils.NOTHING.equals(value)) {
return "";
} else {
throw new IllegalArgumentException(
"Value is no String (class=" + value.getClass().getName() +
", value=" + value + ") and component "
+ component.getClientId(context) + "with path: "
+ getPathToComponent(component)
+ " does not have a Converter");
}
}
if (RendererUtils.NOTHING.equals(value))
{
return converter.getAsString(context, component, "");
}
else
{
return converter.getAsString(context, component, value);
}
}
If a converter is used and RendererUtils.NOTHING is set, we should call
converter.getAsString with empty string as value (right now
RendererUtils.NOTHING is passed, but it must not, because this var is used when
no selection is set by the user and then pass it as null value).
The fix should be done for both 1.1 and 1.2 branches
