> -----------------------------------------------------------------------------------------
>
> Key: MYFACES-461
> URL: http://issues.apache.org/jira/browse/MYFACES-461
> Project: MyFaces
> Type: Bug
> Components: General
> Versions: 1.1.0
> Environment: win xp pro, jdk 1.4.2_06
> Reporter: Eric Hsieh
> Fix For: Nightly Build
>
> When trying to get the values from a SelectManyListbox that has no
> valuebinding, a null pointer occurs when the renderer util tries to convert
> the list of values.
> In _SharedRenderedUtils.java, this section gets called if there is no value
> binding for the component
> // Now, we have a converter...
> if (valueType == null)
> {
> // ...but have no idea of expected type
> // --> so let's convert it to an Object array
> int len = submittedValue.length;
> Object [] convertedValues = (Object [])
> Array.newInstance(arrayComponentType, len);
> for (int i = 0; i < len; i++)
> {
> convertedValues[i]
> = converter.getAsObject(facesContext, component,
> submittedValue[i]);
> }
> return convertedValues;
> }
> Since valueType is null, arrayComponentType is also null and never
> initialized to a value. The Array.newInstance() call fails due to
> arrayComponentType being null.
> Should this array be initialized with Object.class since the array is of
> Objects?
