Steps to reproduce:
1) Navigate to Telerik Silverlight examples app with recorder attached
2) Record a radcombobox dropdown 'Open' action against any radcombobox control in demo
3) Select this recorded step and Run -> Selected Steps

Expected behavior:
Step executes and opens the combobox on demo page

Actual behavior:
Step fails to execute with error below, the failure details suggest the visual tree was not up to date. Adding a coded step to refresh the visual tree (eg. Pages.TelerikComboBoxFor0.SilverlightApp.OwnerApp.VisualTree.Refresh();) and executing both together is able to workaround the problem.
