I want to *use Scriptrunner* to create a *SCRIPTED* Custom Field

[bauerprocessconsulting]

I use the system-customfieldtypes-plugin.xml file for reference when creating Custom Fields using Scriptrunner:

    <customfield-type key="textfield" name="Text Field (single line)"
    <customfield-type key="textarea" name="Text Field (multi-line)"
    <customfield-type key="datepicker" name="Date Picker"
    <customfield-type key="datetime" name="Date Time Picker"
    <customfield-type key="float" name="Number Field"
    <customfield-type key="importid" name="Import Id"
    <customfield-type key="select" name="Select List (single choice)"
    <customfield-type key="radiobuttons" name="Radio Buttons"
    <customfield-type key="project" name="Project Picker (single project)"
    <customfield-type key="multiversion" name="Version Picker (multiple versions)"
    <customfield-type key="version" name="Version Picker (single version)"
    <customfield-type key="userpicker" name="User Picker (single user)"
    <customfield-type key="url" name="URL Field"
    <customfield-type key="multiselect" name="Select List (multiple choices)"
    <customfield-type key="multicheckboxes" name="Checkboxes"
    <customfield-type key="multiuserpicker" name="User Picker (multiple users)"
    <customfield-type key="multigrouppicker" name="Group Picker (multiple groups)"
    <customfield-type key="grouppicker" name="Group Picker (single group)"
    <customfield-type key="cascadingselect" name="Select List (cascading)"
    <customfield-type key="readonlyfield" name="Text Field (read only)"
    <customfield-type key="labels" name="Labels"

One Custom Field type that I'm missing is: "Scripted Custom Field".

Can someone tell me which key to use in order to create a Scripted Custom Field?
