Hello Users,
I was experiencing a problem which might be a Bug in MyFaces 1.1.5 SNAPSHOT
and wanted to know whether I'm the only one seeing this:
java.lang.NullPointerException
at
org.apache.myfaces.shared_impl.renderkit._SharedRendererUtils.getConvertedUISelectManyValue(_SharedRendererUtils.java:147)
....
(Full exception Stacktrace below)
I know what my error was (using a SelectItem[] for the value attribute in a
selectManyCheckbox) but I still think that this should crash with a
NullPointerException in MyFaces.
What's happening is that the converter logic beginning in
SharedRendererUtils.java:96 doesn't result in a valid converter Object which
leads to this exception. Furthermore, the last line of the converter logic:
converter =
facesContext.getApplication().createConverter(arrayComponentType);
expects createConverter to throw a FacesException in case of an error, but the
method internally used to create the converter object
internalCreateConverter() of the ApplicationImpl might return null without
throwing the exception.
Is this a bug?
Cherrs,
Marcus
