Hi, I have a Listbox that allows multiple record selection to be selected and verified; and a Button to carry out the verification action. After that, the Listbox is refreshed so that it won't display those selected records anymore (ex: if there're 10 records and 3 are selected for verification, once the Verification button is clicked, the Listbox will only display 7 records now). The problem is that it works fine in Firefox3.6 but errors out in IE7 with this error: "Failed to process addAft, Object doesn't support this property or method". The Verification logic for my Button is as follow:
1. Run an Update Query to change the Verify field from 'unverified' to 'verified' for those selected records.
2. Run a Select Query to grab only those with Verify = 'unverified' (so that the new ResultSet won't include those records that just got verified)
3. SetModel and ItemRenderer to the List<RecordBean> in step 2.

Please let me know why it does not work in IE7? I'm using ZK 5.0.3 Community Edition. Thanks much..
