i changed the category, since it is a problem with pd (though it affects
externals)

i changed the name, because it is not gui-specific: every object that
defines a savefn() is affected by this (usually only gui-classes do this
because they are the classes where you cannot directly edit the arguments
(being hidden) and which might offer a properties window to change these
arguments)

however: i think it is a great feature that an object is able to change
it's own name (really).
nevertheless, an object should also be able to _query_ it's own name.
this is usually not a big problem because the object assumes that it knows
how it is called (the name the dev gave it).
when using namespaces this is not the case any more.

basically: the object would need a way to easily query it's own name (i am
sure it is somehow possible via weird t_canvas/t_class/t_obj/t_pd/...
pointer magic which is so complicated i will have to re-read to source
code)

the savefn() should provide a way to set object-name and arguments
separately, the object-name should default to the actual name (not the
canonical one) if not set otherwise.

I found the root of the problem, if the GUI object has a savefn, then that
savefn needs to include the whole classname, including the namespace
prefix.

I think  stffn was right, it does apply to all GUIs.

This doesn't happen to all GUI objects, just some.  I think [grid] is one,
but many others work fine with the prefixes.

True, this also happens in Pd version 0.40-2.

This happens on Pd-0.40.3-extended-20071021 on Mac OS X also.  Has anyone
tested this on other GOPs? I know pddp/pddplink works fine.  Also
cyclone/Scope~ also works.  I think this might be an issue with the objects
themselves.

I forgot to mention that it happens to quite many if not all the GUI
objects. At least those in CVSROOT/doc/pddp/about/GUIs-about.pd.
