How get current custom field value and compare it with the new one after update

[Bashar Haydar]

Hi all,

i would like to know if there is a way to catchthe previous/current values selected for a custom field of type check box  or drop-down list with multiple selection.

My case is that i have 5 fields once it's updated a related issue will be created that reflect the new values, for here no problem i used the post-function, but what  i need to send an email to the assignee what changes are done example

filed 1 actions:

   - option1 unselected 

   - option2 selected

thank you.

Hi Bushar,

So in order to get the old and the new value when you update a custom field, you will need a Custom Listener that will listens for Issue Updated events and the script will look something like 

import com.atlassian.jira.event.issue.IssueEvent

def event = event as IssueEvent
def changeItems = event?.getChangeLog()?.getRelated("ChildChangeItem")
def change = changeItems.find {it.'field' == "Checkboxes"}

if (change) {
    def oldValue = change.'oldstring'
    def newValue = change.'newstring'
    // do something with them
}

Hope that sheds some light
