If an element contains an ampersand in some of its attributes (e.g. id="R&D") the JS Recorder records it as "ID exact R&D" instead of R&D hence the the element cannot be found.

The exception is:

Outer Exception Type: ArtOfTest.Common.Design.Exceptions.ElementFindException
     Message: Unable to locate element. Details: Attempting to find [Html] element using
          Find logic
          (Html): [name 'Exact' R&D] AND [tagname 'Exact' div]
          Unable to locate element. Search failed!

     HRESULT: 0x80131500 (Official ID (if app.) = COR_E_EXCEPTION, Error Bit = FAILED, Facility = FACILITY_URT, Code = 5376)
     Call Stack:
          at ArtOfTest.WebAii.Design.Execution.ExecutionUtils.WaitForAllElements(IAutomationHost host, AutomationDescriptor descriptor, Int32 timeout)
          at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.ExecuteStep(Int32 order)

The workaround is either to use IE recorder for the particular step or replace "&" with "&" in the find logic.
