ScriptRunner listener that updates the issue summary

[daniellec]

Hey!

We are using ScriptRunner to calculate number of specific comments for an issue.

This number is stored in a dedicated custom field.

We would like to also update the Issue's Summary with this number, for example:

[Number of comments: X] [Issue Summary]

I understand we need to use a ScriptRunner listener with CustomFieldUpdatedEvent,

Can someone help with the script?

Thanks!

Danielle
