Unsaved TOC error with KeyError 'toc_depth' when XSLT rendering

[Clemens Robbenhaar]

With the current CVS Head try the following steps:

 - create a new Document
 - edit it with the forms based editor
 - create a "table of contents"
 - do not choose "save" or "save and exit",
   switch directly to the preview tab

If I do that I get "KeyError" with the XSLT renderer,
no problem with the widget based one.

Not a very common scenario, I guess ;)

The workaround is to save the TOC first after creating it.

Verify this in Silva trunk.

OK, changed the xmlexport of tocs to assume unlimited when there is no toc_depth attribute. Unlimited is the default in the widgets-based renderer, as well as AutoTOC content type.

However, if you do the steps to replicate, and instead switch back to kupu, you get an error:
  Module Products.SilvaDocument.transform.kupu.silva, line 459, in convert
ValueError: invalid literal for int(): None

[Andy Altepeter (aaltepet)]

Adjusted Module Products.SilvaDocument.transform.kupu.silva, line 463, in convert
So a None depth isn't converted to the string "None", which doesn't int().

Now going to check if the widgets editor can be changed to set a default depth on node creation.

Also added an insert_init.py to the toc widget, which adds the toc_depth attribute. This is the root of the bug, and should fix any other related issues.
