Troubleshooting: Sample Entity Not Displaying in Entities App

Issue:

  • A user has a Sample Entity with a picklist field that needs to evaluate an ESP Expression to display the list choices

  • The expression was tested in a protocol picklist and evaluates as expected in a picklist column

  • The param groups with a “list” as the value did not evaluate as “list” objects when used with ESP Expressions for picklists

  • "The values for a Parameter can be either scalar values or lists", and iterating over the param reference returned a single character in each list row

Solution:

  • ESP Expressions are not evaluated in the Entities app, and this is evident that the list correctly renders in the LIMs app but not on Sample Creation

  • User can change this to a Sample Protocol as a temporary workaround

  • In the future L7 is experimenting with supporting expressions in the Entities app, but this feature is not currently available
