The latest release - which is compatible with VM3 - is 2.1.0.
Hmm..I see the lastest one is 1.2.0 and I have been testing this one.
I don't have any strict javascript errors but looking on the firebug console when the issue exist I have:
updateDynamicUpdateListeners found URL attri undefined Object[select#389-3030customProductData.vm-chzn-select.chzn-done]
dynupda...er=8578 (line 75)
updateDynamicUpdateListeners URL attrib empty dynupda...er=8578 (line 78)
updateDynamicUpdateListeners onchange set URL dynupda...er=8578 (line 81)
setBrowserNewState dynupda...er=8578 (line 102)
UpdateContent URI dynupda...er=8578 (line 21)
I didn't mention about this in the first post but when I refresh the page (F5) the issue is gone ( as well as the "wrong" code I had put above). So, I'm not a programmer but maybe this issue is related with the new dynamic update feature (ajax reload) in VM3...
So once again the issue occurs in the two instances and it's gone after refresh the page:
- we review the products in the certain category using product navigation ( if enabled is on the top of the product page)
- we go to one of the products from generic child variant
Please check this and you'll see what happens
