multiple add to cart problem

i have a combined search and results page created with dataassist, and i have added select and quantity fields to the results table to enable multiple item add to cart.

if i click several check boxes, then only the checked items are added to the cart, which is what i want,

but if i don't select any check boxes, all of the items in the current page view are added to the cart.

In the data assist search server behavior, set the default where clause to:
0 <> 0

Hi Jason,

I tried that for both, around lines 260 and 299

I also tried 'AND ItemID =0', based on the tutorial, but I get the same result

Most likely because the old result is stored in a session.

close the browser completely before testing to end the session.

I tried in FF, Chrome and IE, all new sessions, still have the issue.

The only way I can avoid it is to set the default quantity to 0

set the trigger of the data assist search to use the checkbox.

for the trigger, click the lightning bolt, and select the checkbox from the form.

doing that reloads the form and nothing is added to the cart.

go back to the submit button trigger, send the latest copy of your page and a link where i can see the problem.

I have created a page to simulate the problem with dummy data and uploaded it to my test server.
Sorry for lack of css, just wanted to keep it clean and simple.
I have also separated the search and results to make things clearer.
I have removed the default where string
Several things are apparent.
When adding items to the cart, selecting one or more item and a quantity will add those items (only) to the cart correctly.
If no items are selected and add to cart is clicked, all items on the current page are added to the cart.
On return to the results page, trying to add the same item to the cart again has no effect.

Link to the results page is here

Line 22 must set the default where:

$WADbSearch2_DefaultWhere = "";

change that to:
$WADbSearch2_DefaultWhere = "ItemID = 0";
