This is very strange, seems to be a problem with Seaside: in my image
I have a method in the Seaside-Package

		^ self signal

Maybe you should try to reload the latest Seaside from the
SqueakSource repository.

I am developing in 3.8, if you don't want to be surprised with
undiscovered problems you should probably try this one.

See my original announcement in the SmallWiki mailing list, it
includes migration code to keep your code and all your data alive
while upgrading from SmallWiki 2 to Pier ...


> Where does Smallwiki2 store the data anyway??

Objects, that all live happily in the Squeak image ;-)

Pier was designed to have a prevalence like persistency: this means it
consists of a snapshot mechanism and the logging facilities for
command-objects. Command objects are the key thing, since this is the
only way to modify the model. There is some experimental code (that
already proved to work) but that is not tested in real environments
and that is still lacking some features.
