def c = ComponentAccessor.componentClassManager.getMetaPropertyValues()


def component = getFieldById('components-textarea')
component.setHelpText("----->>Multi Select Field is set to Support " + c.size())

Hi @Nishant Paraskar ,

you are using incorrect id for components field, it should be "components" instead of "components-textarea".

Something like this should work:

import com.atlassian.jira.bc.project.component.ProjectComponent
import com.onresolve.jira.groovy.user.FormField
import static com.atlassian.jira.issue.IssueFieldConstants.COMPONENTS

FormField componentsField = getFieldById(COMPONENTS)
List<ProjectComponent> components = componentsField.getValue() as List

if (components.size() > 1) {
componentsField.setError("Only one Component is allowed")
} else {
