Alias mapping, object not found

Hi Mika,

 

I would suggest that you explore the problematic NameMapping.Sys.oscar.wndFNWND3125.MDIClient.wndFNWND3125 object. Judging by the error, TestComplete cannot find this exact object during the test run. Check which properties are used to map this object in the Name Mapping editor and analyze if their values aren't changed when executing the test. Most probably, not reliable properties were used for mapping. 

I recommend that you watch the following video demonstrating how to work with objects whose properties may change:
