Behaviour initializer fails with No such property b for class

[Yves Martin]

 Hello

In Adaptavist ScriptRunner Behaviour with initializer configured for a script "screen-init.groovy" with method "run",

I receive following exception for each execution:

2019-09-24 14:41:50,119 http-nio-8080-exec-84 ERROR [...] /rest/scriptrunner/behaviours/latest/validators.json [c.o.jira.behaviours.BehaviourManagerImpl] Validation exception.
groovy.lang.MissingPropertyException: No such property: b for class: screen-init
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:66)
at groovy.lang.MetaObjectProtocol$setProperty.call(Unknown Source)
at com.onresolve.jira.behaviours.BehaviourManagerImpl$_runValidator_closure9.doCall(BehaviourManagerImpl.groovy:216)

And I do not understand what is wrong and where this "b" comes from.

Here is the script content:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.bc.project.property.ProjectPropertyService

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def projectId = getIssueContext().getProjectObject().id
def projectPropertyService = ComponentAccessor.getComponent(ProjectPropertyService.class)
def enabledProperty = projectPropertyService.getProperty(user, projectId, "enable-choice")

def firstField = getFieldByName("First")
def secondField = getFieldByName("Second")

if (enabledProperty?.isValid()
    && enabledProperty.getEntityProperty()?.isDefined()
    && "1".equals(enabledProperty.getEntityProperty()?.get()?.getValue())) {
  if (secondField) {
    secondField.setReadOnly(true)
  }
  if (firstField) {
    firstField.setReadOnly(false)
  }
} else {
  if (secondField) {
    secondField.setReadOnly(false)
  }
  if (firstField) {
    firstField.setReadOnly(true)
  }
}

And it seems to me that behaviour executes properly when invoking concerned screen...

So is there a way to get rid of these exceptions in Jira log file?

Thank you in advance for your help

Apologies for the delay in answering this.

When running behaviours from a file you need to add some extra imports.

We mention this here

But essentially add this to the top of your script:

import com.onresolve.jira.groovy.user.FieldBehaviours
import groovy.transform.BaseScript

@BaseScript FieldBehaviours fieldBehaviours

Correct. I have already these statements for most of my behaviors but not in some initializers. Thank you for your support.

@Matthew Clark This information seems to be missing from the current docs.

I understand it is hard to find and have raised an internal bug already to make it more obvious in the guide.

It is under the heading "Tip for IDE users" which is just under this section here.

I think if we just make a new heading for this it will make it easier to find so I will suggest that.
