I try to set field options for 'Priority' field with Behaviours initialiser. Jira profiling shows that my script runs for about 0,05 - 0,06 sec. But when I open or refresh issue form I have about 1 - 2 sec to click on 'Priority' so it shows me all available priorities instead of script chosen variants. So the button to change field value appears before script end its work and if I click in this time gap my script not in time to apply options. What am I doing wrong?
