----------------------------------------------------------------------------
Key: MYFACES-149
URL: http://issues.apache.org/jira/browse/MYFACES-149
Project: MyFaces
Type: Bug
Versions: 1.0.9 beta
Environment: Tomcat 5.5.9
JDK 1.5.0_01-b08
Reporter: Jochen Schw�rer
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.component.UISelectMany.getConvertedValue(UISelectMany.java:295)

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>
