I'm using the 0.6.1 beta of e commerce with ss 2.4. The module extendedproductvaraiations seems to work globally, but i cannot create the variations sleceted from the variations list on the Product Variation tab in the Product editor. I click on createvariations and seems to go, got the silverstripe logo but when the page is reloaded is not even on that tab, and obviously no variations are created.
any suggestions?

yeah, and problems seem rather odd... I create a variation Option Group, then add Vaiation options...in the varation options tab the system asks for extended product variations, which let's you add text, price and choose a product from the dropdown menu. ok, then we go to the product we need to manage, product variation tab, it asks you which option group you want for your product and then i assume that weith "Create variations" you can actually add the variation to your product. nothing happens.
and that's not all. if we skip the create variations step, on our product we can actually see a dropdown menu with the choices we have entered, if we DO create variations, this drop down shows only the name of the product and the extende product variations we entered are disappeared from variation option tab.

try it, because it's an useful extension but it's not working and there is no documentation about it, not even what could be the correct workflow to operate with variation (i could have done something wrong, but who knows with no docs?)

Which version do you use?

but into the last trunk ( not downlodaded from extensions section ) there is already extension.
