How to auto populate custom field(text) based on another custom field(checkbox) using script runner

anil musunuru

I have a Custom field(checkbox field) Fruits with values Apples,Oranges,Lemon.

I have another Custom field(Text field) Shop,

When Apples is checked then i need to auto populate Shop custom field with value (TechDev)

When Oranges is checked then i need to auto populate Shop custom field with value (TechArch)

This is in a view/edit screen so i am looking for script listeners to do the job

I think we need to clarify the requirement first.

"Auto populate" is usually used to mean "when a field is presented to the user for them to put data in it, fill it in for them, with a suggested value, but let them continue to put what they actually want in the field if they don't like the suggestion".  There is an often unstated assumption that if you're in an edit, you do not overwrite the current value (Mostly because that would *really* annoy your users, having to re-enter the current value on every edit)

But, you mention listeners, which leads me to the second possible meaning, which is that you don't want the users to be able to over-ride the pre-populated value, you just want to set the value based on data on the issue at a certain point in the lifecycle. (A second question in this case is whether you ever want them to be able to edit the value)

So, three options:

• If you want to pre-populate, but allow the user to override a value on the create or edit, you need a Behaviour
• If you want to set a value after they commit their data on create or transition, and allow them to change it later, then you need a listener or post-function
• If you want to calculate a value that the user cannot change, a scripted field might be a better choice (scripted fields let us down when we want select-type fields that are searchable)
