Similar issues here. Updated to DevExpress 14.2 and now the method calls on grids like "ClickCell" or "HoverMouseCell" on my DevExpress.Xpf.Grid return a generic error and the test stops. Looks like the cell stuff needs some attention. Record/Playback only uses generic click(x,y) which is not feasible.
An error occurred.
Possible reasons:
The application stopped responding.
The application was compiled incorrectly (see the Open Applications topic in the help system).
An error occurred in TestComplete.
