System property glide.ui.list.optimize set to false causes lists to not display values for columns from extended tables except for the lowest in the table hierarchy

When the system property glide.ui.list.optimize is set to false, lists do not display values for columns from extended tables, except for the lowest one in the table hierarchy.

1. Add a new column to the cmdb_ci_win_server table named Test Column, type String, max length 40.
2. Go to cmdb_ci.list and configure the list layout to add these columns to the list:
Hardware Status [Hardware]
Operating System [Computer]
Test Column [Windows Server]
3. Filter the list for Name OWA-SD-01
4. Add the value "Test" to the Test Column for this record.
5. Select the value Installed for the Hardware Status [Hardware] column. (You might need to open the record in form view, add the Hardware Status field to the form and select Installed on the form and save.)
6. On the cmdb_ci list (filtered for Name OWA-SD-01), you should see the following values for each of these columns for the OWA-SD-01 record:
Hardware Status [Hardware] : Installed
Operating System [Computer] : Windows 2003 Standard
Test Column [Windows Server] : Test
7. Add a system property glide.ui.list.optimize (type: true/false) and set its value to false.
8. Refresh the cmdb_ci.list, filtered for Name OWA-SD-01. For the columns coming from extended tables, only the value for the lowest table in the hierarchy, in this case Windows Server [cmdb_ci_win_server], is displayed. The values for Hardware Status [Hardware] and Operating System [Computer] are not displayed.

After carefully considering the severity and frequency of the issue, and the cost and risk of attempting a fix, it has been decided to not address this issue in any current or near future releases. We do not make this decision lightly, and we apologise for any inconvenience.

Re-enabling the value for the property glide.ui.list.optimize to true will show the values for the columns from all the extended tables.
