On a site I'm working on the slideshow breaks when there are multiple slideshows present.
Roughly summarised, the problem is that the slideshow count is appended in the wrong place:
- the HTML id's like "views_slideshow_main_foo" and "views_slideshow_main_foo-1"
So one of the divs has the numeric ID in the settings, but not in the source. This causes an exception (can't set targetId on undef) in views_slideshow_cycle.js::16.
I patched a very temporary (ugly, bloaty, rubbish) fix in our local version that added the non-numeric *and* the numeric JS config to the source (because of ordering this works out fine, but it adds weight) at the same time.
Let me know if you need any further info / debugging. Can't point you to a site as it's local at the minute :(
