Symptoms


Dot walk fields (for extended tables such as Task) do not display any value on list view and reference lookup on form view

Release


All

Cause


There is a column in Dictionary other than the Number column, whose attribute is set as display=True on Task table 

Resolution


Change the value for display attribute to true for number column on task table, and any other column's Display attribute should be false in dictionary

Additional Information


By default, number is the display value=true for all task and task extended tables, such as incident, sc_req_item and sc_request table. Because of the display value changed to other column, the reference fields didn't have display value to refer to so it display blank (show xml of the record will show the sys_id of the record)

Below are the information form documentation for your reference:
 "Extended tables inherit the display value of the parent table. Setting a separate display value for the extended table overrides the parent table's display value."
