Scripted Behavior to restrict checkox selction upto 2 values on create screen

Sudheer Kumar Vempala_em1ae6

Hello Commity,

I am tring to restrict a checkbox field name "Flagged" to allow upto 2 values on create screen. The following script is working for when user select 2 options and throwing error if they select more than 2 values.

But script is aslo throwing error if they seclect 1 value and not select any value.

looking for some help to optimize it.

import static com.atlassian.jira.issue.IssueFieldConstants.*
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.scriptrunner.runner.util.UserMessageUtil

def field = getFieldById(getFieldChanged())
def ComponentsField = getFieldByName("Flagged")
def selectedValues = field.getValue() as List<String>

if (selectedValues.size() <= 2){
ComponentsField.setValid(true)
ComponentsField.clearError()
}
else
//if (selectedValues.size() > 2)
{

ComponentsField.setValid(false)
ComponentsField.setError("Maximum 2")

}

Hi @Sudheer Kumar Vempala ,

please confirm that you put that code to Flagged field.

Then try the following code :

import static com.atlassian.jira.issue.IssueFieldConstants.*
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.scriptrunner.runner.util.UserMessageUtil

def field = getFieldById(getFieldChanged())
def selectedValues = field.getValue() as List<String>


if (selectedValues == null || selectedValues.size() <= 2){
field .setValid(true)
field .clearError()
}
else
//if (selectedValues.size() > 2)
{
field .setValid(false)
field .setError("Maximum 2")

}

Please let me know,

Fabio

Hello Fabio,

Thanks for the quick reponse.

Yes correct script is mapped to "Flagged" field.

I have tired the updated script with additon of "null" now script is working 0-selection and 2 but the weird part is still 1-sections is tworing error.

I tired differnt version where count <=1 code is failing if user selcects one option.

if (selectedValues == null || selectedValues.size() <= 1

Hey @Sudheer Kumar Vempala ,

I probably get your issue. Please could you provide information about checkbox options? Probably there are spaces in your options

Try this code :

import static com.atlassian.jira.issue.IssueFieldConstants.*
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.scriptrunner.runner.util.UserMessageUtil

def field = getFieldById(getFieldChanged())
def selectedValues = field.getValue() as ArrayList<String>


if (selectedValues == null || selectedValues.size() <= 2){
field .setValid(true)
field .clearError()
}
else
//if (selectedValues.size() > 2)
{
field .setValid(false)
field .setError("Maximum 2")

}
