setValue changes back to previous value on callback function

[raed1]

Hello everyone,

I am trying to set the value of a reference field on a form by checking two things:

1. User accessing the form is part of a certain group.

2. The required checkbox selected.

To check if the user is part of a certain group I have made a script include that I am calling from a client script.

var CheckMembership = Class.create();
CheckMembership.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
   checkMembership: function() {
   return gs.getUser().isMemberOf('Group A');
   },
   type: 'CheckMembership'
});

And this is the client script:

function onSubmit() {

var ga = new GlideAjax('CheckMembership');

  ga.addParam('sysparm_name','checkMembership');

  ga.getXML(CheckMembershipParse);

  function CheckMembershipParse(response) {

            var answer = response.responseXML.documentElement.getAttribute('answer');

            if (answer == true && g_form.getValue('checkbox_1') == 'true') {

                  //sys_id of Group A

                  g_form.setValue('assignment_group','4b576a32db13f280586e5bcscf931s02');

            }

                  alert(answer);

}

}

I noticed that the value of the assignment group does change to the one I want it to for a split second. However on opening the record again, the assignment group reverts back to its previous value. I also found out that the code works as expected if I set the value of the assignment_group outside the callback function.

Any help on this would be greatly appreciated.

Thank you,

Raed

Hi Raed

Sanjiv is right. Just last one thing.

In order to avoid hardcoded sys_id, i would suggest to change a little your code.

Create a brand new system property in the table named 'sys_properties'

e.g. myDefault.assigment.group as String and populate the value with your sys_id

than change the script include function to be something like

checkMembership: function() {
   var out = '';   
   if(gs.getUser().isMemberOf('Group A')){
         out = gs.getProperty('myDefualt.assigment.group');
   }   
   return out;
 }

the client script will be than

function onSubmit() {

var ga = new GlideAjax('CheckMembership');

ga.addParam('sysparm_name','checkMembership');

ga.getXMLWait();

var answer = ga.getAnswer();

if (answer != '' && g_form.getValue('checkbox_1') == 'true') {

                  //sys_id of Group A

                  g_form.setValue('assignment_group', answer);

            }

}

Cheers

Hello Sanjiv and R0b0,

Thank you so much for the quick response. I think I should have mentioned this earlier but I am using these scripts on a scoped app and from what I have read so far, getXMLWait doesn't work on scoped apps (The value of answer returns null). I have taken a different approach (probably a better one) by assigning roles to the group members so I can just use the client side g_user, instead of using a script include. However, it would still be interesting to know if there is any work around to this.

Thanks once again,

Raed
