#2281:

  • Moved check if context contains a parameter of the requested translated name to the front of the loop
    • Reason is that ResultsParameter queries for a parameter "Results" which doesn't exist in its own context
  • Added a flag to suppress the type check in LookupParameter's GetValue
    • Default value of that flag is true, so existing code is not affected
    • Reason is that ResultsParameter queries for ResultCollection with a generic type e.g. IntValue which don't match
  • Replaced some ContainsKey/Access combinations with TryGetValue
