How do I get the Service Management Request Type name in behaviours?

From ScriptRunner 6.1.0, you can call the getRequestTypeName method within your behaviour scripts to get the name of the current Service Management Request Type that the user is interacting with.

How do I get the value of the current issue’s custom fields with behaviours when on the edit screen?

Use the underlyingIssue variable in a behaviours script to find the value of current issue’s fields. This variable is available in any behaviour script, however, it will be null on the Create screen because the issue does not exist at that point.

import com.atlassian.jira.component.ComponentAccessor

def myField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjects().findByName("TextFieldA")
def fieldValue = underlyingIssue?.getCustomFieldValue(myField)
CODE

When using the underlyingIssue to retrieve the values of the current issue’s fields those values are obtained from the issue and not the values within the current form.
