Subject RichFaces + Tomahawk Schedule = bug when you select a schedule entry
Date Tue, 29 Jan 2008 10:43:46 GMT
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]-

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