Hi there,

we have installed the trial version 5.25 on our system. With this version I treid to use the querystring parameters for a variant pre-selection but this results in a null reference exception. Here is what I tried to do:

- I created a variantgroup
- then I created variants to this group
- The variant still works in normal selection on the detailpage of the product
- then I tried to use the querystring:

http://192.168.67.46/SmithShop/SmithShopDetailpage/tabid/310/ProductID/4/Default.aspx?variantid=23

the variant is one of the displayed options in the variant grid of the product (in this case 4)

In the EventLog I get these 2 informations:

Hi Kevin,

the productID is included. The Page uses friendly URL (configured in the web.config of DNN). This Option converts/splits each parameter of a querystring to slash separated url parts. See here:

http://192.168.67.46/SmithShop/SmithShopDetailpage/tabid/310/...
...ProductID/4...
.../Default.aspx?variantid=23

If I convert the requestURL to something like this:

http://192.168.67.46/SmithShop/SmithShopDetailpage/tabid/310/Default.aspx?productid=4&variantid=23

the same error occurrs.

Best regards,
Alex
