Behaviour : Checking 'None' option , all other checked options should be unchecked

[nallu]

Hi,

I have created a 'multi select checkboxes' custom field 5 option including 'None'.

It is a single field with multiple checkboxes as options.

 

I am trying to write a behaviour script for that field such way that if 'None' option is checked, then all other selected option will be unchecked by automatically. Also, 'None' will be unchecked by selecting any other option.

Here is my code,

def gatingMechanismField = getFieldById(getFieldChanged()) // Getting Gating Mechanism field object
def gatingMechanismValue = gatingMechanismField.getFormValue(); // Getting gating mechanism values


if(gatingMechanismValue == '13405' )
{
 gatingMechanismField.setFormValue('13405')
}
else
{ 
 List list = gatingMechanismValue;
 
 if(list.contains(13405))
 {
   list.remove(13405);
   gatingMechanismField.setFormValue(list)
 }
}

It doesn't work. 

Observation: 

- getFormValue() return's value of the option (say: 13405) as a string when 'None' is chosen

- If we choose more than one option , it returns array list (ex: [13405, 13400. 13401])

Can someone please help me on this.

Hi Nallu.

I've done some minor modifications to your code, where you had a few dangerous statements that could lead to exceptions. Also, if I'm not mistaken, the value isn't a long, it's a String.

Try this:

def gatingMechanismField = getFieldById(getFieldChanged()) // Getting Gating Mechanism field object
def gatingMechanismValue = gatingMechanismField.getFormValue() // Getting gating mechanism values

if(gatingMechanismValue instanceof List) {
    def list = gatingMechanismValue as List
    if(list.contains('13405')) {
        list.remove('13405')
        gatingMechanismField.setFormValue(list)
    }
} else {
    gatingMechanismField.setFormValue(['13405'])
}

Btw I could be wrong about the ids being strings, if I am wrong, substitute all of the 

'13405'

for

13405
