Data for search field consists of id ( like 32987-saf82qef-asdfr3hj-asas712) and name. Only name is shown. I can't set default value for that customfield. I tried to give the id as default value but got "Unknown id:" and the value is then {1}.
What I'm trying to accomplish is to show the field in issue details with default value of "Please select...". Which would be a dummy row in source database.
