If you use the "binding" attribute on your component, to bind the component instance to a backing bean instance:
<h:outputText ... binding="#{mybean.myOutputTextComponent}" .../>
then you will have to be restoring the backing bean instance (if it is in request scope, or if it doesn't exist already) as part of the Restore View phase.
The particular exception reported above, however, implies that the BasePageBean$1 class being referenced does not have a public, no-args constructor.

First thing that strikes me: why is the "restore view" process trying to
restore an instance of a backing bean? Restore view only restores the
UIViewRoot and its components, not backing beans.
Well, that depends on the circumstances ...

Are you using the t:saveState component perhaps?
And as Bruno noted, the full stack trace is really required to help with
this. Typically when this happens, you'll get about 4 ERROR log messages
generated together. The first is the most useful, but it looks like
you've just given us the first 4 lines of the last exception.
Cheers,
Simon
