Need to fire event based on value change of custom field

[Rizwan Rizvi]

Basically what I need is below

I have a custom field 'Special' with values None, A and B as drop-down option. By default the option is set as NONE. A user could change option A or B. When someone choses a value to A or B, an email needs to be send out accoridngly to a fixed email chain.

Need to send out Issue ID and Summary for the issue in the email as well as the current user who set it.

How can I accomplish this?

I tired behaviour plugin as described in this post and also used Mizan's option but think I am don't have the requisite background to code this. Apreciate any help

Hi Rizwan ,

Use the exact script provided by me .. use fieldChanged instead of your customfield id .

Also the script is for an older version of Jira , there are some api changes which you will need to update . eg: ComponentManager -> ComponentAccessor .

IF you use the above script then it will send an email whenever the user changes the value of the field before submiting it . I think you should use a post function , may be you can use send custom email post function by script runner plugin
