On change event for custom field

[Lior Zadok]

Hi,

Is it possible to fire an event based on a change of a custom field. I know I can use the Issue Updated events but I am afraid it will be too broad.

I have a request to update/review all the Custom Rank fields of issues on a certain project once Custom Rank gets updated on a single issue. 

too much ?

Not without hacking the core of Jira's code.  Events are fired as part of the workflow and on a number of operations.  But the events are all "something happened to issue", not "something happened to field".  The event contains a list of all field changes, so your listener can catch that and have "if rank field didn't change, then exit" as almost the first line.

Secondly on the ranking - you're going to run into scaling issues if you try to update all the ranks on a medium or large project.  It's going to be a lot of work when you've got more than a few thousand issues in it.
