I am trying to set up a microflow to parse the enumeration values in my excel importer module. When writing my expression, i get a few lines in and then get an error and the expression editor becomes unresponsive. I don't think i had this issue in the previous version of Mendix (now running 10.5.0). I get this error: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index') at System.Collections.Generic.List`1.get_Item(Int32 index) ...... Any help would be appreciated.
