How to make one variable readonly after task is closed

[Gopal14]

Hi Team,

for making sc_task variables readonly, I have written a UI Policy applies on catalog task and below is my script.

Now I have another variable on task form which is mandatory, after saving the record variable is automatically changing to readonly. however I want that variable readonly when state is closed complete,  I have used below code, but it is not working. means when catalog task state is in open or work in progresss, at that time also variable is readonly, I want that to be editable.

function onLoad() {

   //Type appropriate comment here, and begin script below

    var shortDescription = g_form.getValue('short_description');

    var state = g_form.getValue('state');

      if (shortDescription == 'Confirm Receipt of Old Machine' || state == 3) {

    g_form.setReadOnly('confirm_which_stockroom_this_has_been_returned_to', true);

   }

}

Note: Order of UI Policy is 100

           Order of Client script is 200

Hi @Gopal14 ,

try below code.

function onLoad() {
   //Type appropriate comment here, and begin script below

    var shortDescription = g_form.getValue('short_description');
    var state = g_form.getValue('state');
      if (shortDescription == 'Confirm Receipt of Old Machine' || state == 3) {
g_form.setMandatory('confirm_which_stockroom_this_has_been_returned_to', false);
    g_form.setReadOnly('confirm_which_stockroom_this_has_been_returned_to', true);
   }

}

HI @Runjay Patel 

why we are using setMandatory here?  I am having issue with ReadOnly

Hi @Gopal14 ,

Is this worked? if yes then reason is you can not make field read only if field have empty value with mandatory.

Hi @Gopal14 ,

It seems the field is becoming read-only due to the if condition:
 if (shortDescription == 'Confirm Receipt of Old Machine' || state == 3)  instead use  if (shortDescription == 'Confirm Receipt of Old Machine' && state == 3)
OR , simply 
if (state == 3) 

If you are using the if condition with ll operator the onload script execute even if short description condtion matches.
