Hello Bruno, I found the problem
it was caused by a clash between pinpointing ext-scripting onto the
entire projects path and the classloader hierarchy.
Myfaces tried to load the class internally which then should have been
served originally from spring and cglib, and since ext-scripting had
higher priority it took over and served the class falsely.
I cannot fix that for now, but for such cases I added a bypass:
Following: use
<context-param>
<description>a comma separated whitelist of root packages which
are compiled those and nothing else
will be compiled during all compile stages, all other files
stay permanently as they are
</description>
<param-name>org.apache.myfaces.extensions.scripting.PGK_WHITELIST</param-name>
<param-value>uk.ac.ebi.intact.editor.component</param-value>
</context-param>
to pinpoint ext-scripting to the packages hosting the reloadable
artifacts then it should start to work (do not forget to fetch the
latest version from the trunk or 1.0 branch - I fixed another bug
regarding whitelisting along the way)

I will try to have a smaller app, but cannot promise anything as it is not a
priority (just yet!). Thanks Werner :)

Bruno, can you isolate the problem to a small sample
so that I can have a look at it on friday?

Actually not yet, unless you want to use those beans dynamically via
ext-script, that is not yet supported (only pure jsf beans are)
I will look into the issue on friday however, when I am going to pick up
the work on Ext-Scripting again.
Normally I cannot really think of an issue here, because all
Ext-Scripting does is mistly to provide its own el resolver
which only triggers if the class is a dynamic one, if not it resolves to
the other resolvers in the chain. There is no real magic going on
which interferes on class level which should prevent cglib to work.

Hi,
I am testing the ext-scripting module, which is really a great time
saver :)
However, there seems to be some problems with Spring bean proxies that
I use
in my project as managed beans.
For instance, I have a PublicationController, that extends an
AnnotationController. Spring creates a CGLIB proxy of the former, and
then I
get this exception when using ext-scripting. Any ideas?
