Accordion Problem with latest svn version

Accordion Problem with latest svn version


Hello,
I use the latest svn version and jQuery 1.3. I now get this error
using an Accordion:
The Accordion get displayed OK and when I click on a header, it opens
the correct part.
But after this I get this error and the Accordion is no longer responding:
o.toShow is undefined
[Break on this error] o.toShow.add(o.toHide).css({
ui.accordion.js (Linie 359)
Where is the problem?
Greetings,
Stefan Sturm
