This issue is to document an error 500 that we were getting when trying to select an axis value in the Logical Definition tab, when editing the logical definition or the necessary conditions, for an axis that has no value set specified, such as Serotype or "Genomic and Chromosomal Anomaly" and Measurement (which should in fact have had an value set specified).
These exceptions should be caught and a more user friendly message should be shown, and continue to prevent the user from editing values for such axis.
