Error in TBUI - SBL-DAT-00223

Hi,

We are experiencing some isses with TBUI.  We have build a standard TBUI with a couple of views.  The problem is that everytime we get to one specific view (same view every time), we get the following error:

We detected an Error which may have occurred for one or more of the following reasons:

An error has occurred finding your prior place in the system. The record no longer exists or is not available to the view. Please try a new query.(SBL-DAT-00223).  To add to the confusion, it only happens in the thin client, but it works fine n the dedicated client.
