How to set the value of user picket custom field

[Aron Felberbaum]

Would like to set the value of a custom user picker filed in transition post function

[Nic Brough -Adaptavist-]

You'll need an addon that provides such a post-function, or one of the scripting options like Script runner.

Once you've decided which route to take there, then we can probably help you (although it's "get user, put user in field" really)

[Aron Felberbaum]

Which addon would you recommend

[Nic Brough -Adaptavist-]

Script runner. Always. (I'd have said that before either Jamie or I joined Atlassian, it's the one I've always turned to when something "clever" is needed)

[Aron Felberbaum]

I have Script Runner installed, I'm still new to Jira, could you provide sample code. I'm looking to set user picker custom field to a specific user.

Sorry Aron, missed the email update. I just rummage through Jamie's docs for examples - https://jamieechlin.atlassian.net/wiki/display/GRV/Script+Runner https://jamieechlin.atlassian.net/wiki/display/GRV/Post+Functions+With+Comments might be a good start though, as it's got custom field code and some stuff around users.

Was trying the script below and it does not work, following is the error from the log file.
