Clarity supports URL Attributes. Valid external links should be handled correctly. Users get confused if valid links are causing unexpected server issues.

Some characters, like "%2", on an attribute of type URL are causing an exception on the Classic UI Project List view.

Steps to Reproduce: 

  1. In Studio, create a new attribute on the Project object, of URL DATA TYPE 
  2. Add the attribute to the Classic [Edit Layout] and [List] Views 
  3. Navigate to Home, Projects List
  4. Find a project to open and edit 
  5. Add some value to the attribute of URL type, as the following: http://domain/site/loc/03%20-%20xyz4%20-%2 
  6. Save the changes to the Project 
  7. Make sure the Project List view is displaying the URL attribute as a column  
  8. Refresh the Project List view (or open it) 

Expected Results: The Classic Project List view is displaying the new value added on the URL attribute of the project.

Actual Results: The Classic Project List view does not display. Instead an error is thrown:  [en - Error][EN - ERROR]  [en - Unable to process request - Server or Network error] 


Release : 15.x

Component : CA PPM STUDIO



Workaround: Reset the Project List View and do not configure this URL data type as a column. 


Fixed in Release 16.0.0
