Identifier overrides the username



A grid is configured to display results using a data page from a database table. A dropdown control is used instead of an identifier to display the username. 
In the database table, the corresponding user identifier is saved instead of the operator's username.
When launching the screen the first time, the username displays. After refreshing the screen (using a button in UI), the identifier overrides the username.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create a table with a data page
  2. In the table column, add a dropdown and provide the list source as a data page.
  3. Provide a property for the value. The property for display text is a different identifier.
  4. Add a Refresh button at the top of the table.
  5. Launch the portal.
  6. Change the dropdown value.
  7. Click the Refresh button.

Root Cause

When the dropdown source is configured as a parameterized data page, in the read-only case, the parameter values are sent to the pzGetCaptionValue Rule Utility Function (RUF) in which the Parameter string is split with a ':'. This logic fails when the ':' is present in the parameter values.
