Hi,
I've a project that uses RichFaces and Tomahawk on a WebSphere 6.1
server. The problem comes with the t:schedule component. When you try
to get the selected entry in the value action, you always get a null.
This is code:
public String actionEntrySelected() {
// Here this always return null
ScheduleEntry entry = getScheduleModel().getSelectedEntry();
}
And this is the full exception:
[29/01/08 11:28:05:997 CET] 00000023 WebApp E [Servlet Error]-
[Faces Servlet]: javax.faces.FacesException: #{scheduleHandler.
actionEntrySelected}: javax.faces.el.EvaluationException:
java.lang.NullPointerException

I've been trying to find a workaround for this and downloading the
latest nightly builds without success. Any comments would be really
welcome.
Best regards,
