Checkboxes options as required

[SRIDHAR]

I have a checkbox custom field and it has 5 options. I want all the 5 options to be required. How do I make sure the user has selected all options before submitting the form. How do i make all the options as required ? All we have now is a field as required but how do we make the options as required ?

Solution and I fixed it.

Created a validator in workflow on create issue. Used built in script runner to check a customfield checkboxes values. All the checkbox field is required field. All the checkboxes need to be selected to create an issue.

cfValues['Please acknowledge'][0].getValue() == 'option1'
cfValues['Please acknowledge.'][1].getValue() == 'option2'

cfValues['Please acknowledge'][2].getValue() == 'option3'

cfValues['Please acknowledge.'][3].getValue() == 'option4'

Thank you for your suggestion.

You'll need a validator to do that in workflow.

The standard "mandatory" field stuff will accept any one (or more) options being selected as "this has been filled in".

I tried to add a validator on create issue and mentioned by conditions as

cfValues['Please acknowledge'][0] == 'Yes'
cfValues['Please acknowledge.'][1] == 'Yes'
cfValues['Please acknowledge'][2] == 'Yes'
cfValues['Please acknowledge.'][3] == 'Yes'

It  validates the checkboxes but it won't let me create the issue. I am getting the error message when i click create issue button , please select all the checkboxes .
What am i doing wrong. Please help me out. 

I see this message in logs
