How to fetch the data of component using behaviour script runner

[Nishant Paraskar]

As i used validation on component (to select/restrict  to   one field only )

------------------------------------------------------------------------------

1st i tried this 

import com.onresolve.jira.groovy.user.FieldBehaviours
import org.apache.log4j.Logger
import org.apache.log4j.Level
import groovy.transform.BaseScript
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.bc.project.component.ProjectComponent

def component = getFieldById('components-textarea')
List <ProjectComponent> result = component.getFormValue() as List

if(result.size() >1)
{

component .setError("Only one Component is allowed")

}

else {
component.clearError()
}

------------------------------------------------------------------------------

 2 ] I tried  to get atleast size of selected element 

def c = ComponentAccessor.componentClassManager.getMetaPropertyValues()

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

------------------------------------------------------------------------------

Help me to put validation on component field  . My Requirement is to select only one field from System component field .

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 {
    componentsField.clearError()
}

Hi @Hana Kučerová 

The code you provided is very effective, I use this method to get the name of component, but when I get the comment, I find that the comment information is not valid, here is my code, when I comment the definition of variable name, the last three lines of code are valid, if I do not comment, the last three lines of code are not valid. Can you help me see why, thank you

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

def name = components.getAt(0).name

def com = getFieldById('commentLevel')

def text = """ this is a text  """

com.setHelpText(text)
