Could not serialize state: org.apache.myfaces.component.html.ext.HtmlDataTable

[Matthias Kahlau <mk...@web.de>]

Hi!


I use t:saveState to save the state of a whole Backing-Bean. But I get the
following NotSerializableException now:

Why is the org.apache.myfaces.component.html.ext.HtmlDataTable not
serializable? Do you know any solutions?
