Android Question Problem with Try Catch and Wait for

' This will work Ok if the is error in DoSomething() - '
Try
    a = DoSomething(...)

Catch
    Log(LastException) ' Catch works and traps the error
End Try

' However if DoSomething() returns resummable and an error occurs in DoSomething()
'  then and exception is throw in the DoSomething() sub and the App halts with an exception report. i.e.
Try
    wait for (DoSomething(...)) complete( a as int) ' Exception thrown by DoSomething() and App halts.
    
Catch
    Log(LastException)    ' This does not catch the exception in DoSomething().
End Try
