For example, "when field "x" takes value "y", set field "i" to value "c"".
In others words, I want to make a calculable text custom field (I use plugin "Jira misc custom fields") which takes value depending on some time condition (like "when "time"="current time"+30min?, custom field takes value (text) "red").
I've already made another custom field, which takes current time and adds to it 30 min and it works fine.
Аs I understand, this script ran only one time: when I creating an issue. How it will be initiated at described conditions (when issue already exists)?
Is it even possible: to change existing issues using a scripts?
Thanks.
