Ideas on how to sync a Custom Field between a parent and sub-task using Script Runner?

Question

Any tips/tricks using Script Runner to keep a Parent Story Custom Field in sync with the Sub-Task for that story?

I'm able to copy / propagate the Custom Field into the Sub-Task on creation using a Templates Add-on but I'd like to keep the Custom Field in sycn AFTER the initial creation of the Sub-Task. I'd like the parent and the sub-task to mirror each other for certain fields without having to manually update the Sub-Task

Hi Thanos,

do you have a template of script to show me how to sync an Epic and linked User Story custom field? The cf has the same name in both.

Thanks in advance,

Michele

hi Darren,

I suppose you can use a listener that in every issue update will check parent's custom field value and if this value in the subtask is different then update it. Also if you do not want the custom field value in the sub task to be editable then maybe a scripted field ?

If you could provide a use case ?

cheers, Thanos
