As per my project requirement i have changes the custom field from text to Labels, While i am updating the values of custom filed i am getting groovy script error. Please suggest what could be the approch.
Error Stack :
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Set
CustomField cfEcpId = cfManager.getCustomFieldObjectsByName("ECP ID Label").first();
cf.updateValue(fieldLayoutItem, issue, new ModifiedValue(currentValue, newValue), new DefaultIssueChangeHolder());
Ah, good, that's the right way to approach it.
The problem you have is that your script is not pushing the right type of data into the label field.
A string field is a string of letters. A label field is a collection of individual labels, each of which holds a string that is the name of the label.
In your code, the "newValue" going into the changeHolder needs to be a collection of labels. You'll need to read out the existing labels as a collection, then take the string you want to add to them, convert it into a set of labels you add to that collection, and post that back.
@Adhikari Jitendra Kumar DasI am interested in getting the code for this... I'm assuming you are running it in the Script Console?
I had come up with a solution that will effectively accomplish my intent over time with this post: https://community.atlassian.com/t5/Jira-Core-questions/ScriptRunner-Listener-Copy-free-text-custom-field-value-into-a/qaq-p/743690
However, being able to copy the free text values over to the new label field without having to wait for user-generated events would be amazing as some of our issues may never be edited.
I have multiple projects that use variations of the same base workflow. The variations depend on the requirements of the project or issue type. The variations mostly come in the form of new statuses ...
