It appears that the form_parameter variable of ::xowiki::Package isn't getting reset.

In /xowiki/tcl/package-procs.tcl, the ::xowiki::Package create instproc was commented out for some reason, so when a new ::xowiki::Package was getting created in /xowiki/www/index.vuh, it wasn't getting created cleanly/correctly.

Restoring that instproc seems to do the trick -- at least the image object gets created and the page will display once you navigate back to it. However, the image object creation step return an error from the ::xowiki::Link::image render proc:

This looks like it's probably due to a typo, but I can't figure it out.

The problem with the ::xowiki::Link::image render instproc is that it calls [my info parent] which returns ::xotcl instead of ::xowiki::File as it should.

Since ::xowiki::Link::image is ultimately just an ::xotcl::Object, it's not clear where its parent would ever get set. In fact, [my info vars] on a link image object returns just these vars: package_id folder_id label name lang type stripped_name.

So should ::xowiki::Link have a superclass, say, ::xowiki::Object? Or does parent need to get set at initialization of an object? Or is parent something that needs to be computed via an instproc like resolve?

Gustaf, I know that you said you're going to provide a fix with a 0.34 version, but if you wouldn't mind thinking aloud here about this stuff, it would certainly help us all to understand how to work with your packages. Thanks!
