Description

When no selection is made in the selection list the following exception occures:

java.lang.NullPointerException
org.apache.myfaces.renderkit._SharedRendererUtils.getConvertedUISelectManyValue(_SharedRendererUtils.java:183)
org.apache.myfaces.renderkit.RendererUtils.getConvertedUISelectManyValue(RendererUtils.java:792)
org.apache.myfaces.renderkit.html.HtmlListboxRendererBase.getConvertedValue(HtmlListboxRendererBase.java:143)

javax.faces.webapp.FacesServlet.service(FacesServlet.java:109)
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:115)

I fixed it by adding the following code to the beginning of _SharedRendererUtils.getConvertedUISelectManyValue() in both places (javax.faces.component and org.apache.myfaces.renderkit)
<code>
if (submittedValue == null)
{
return submittedValue;
}
</code>
