g_scratchpad not working

vivektietkumar · ‎07-08-2017

Hi All, I am trying to learn using g_scratchpad variable in business rules and have made a simple program that is not working, so request some guidance.

1. I have a table called check-in and it has a reference field called guest.

2. I have a table called Guest and that has a field called VIP

3. I want a message to be shown using g_scratchpad when someone tries to checkin a VIP guest.

4. I created a display business rule on checkin table (Get VIP Flag) with the following script:

(function executeRule(current, previous /*null when async*/) {

g_scratchpad.vip='current.x_53167_hotel1_guest.vip';

})(current, previous);

5. Then I have the following client script (Alert for VIP)

function onChange(control, oldValue, newValue, isLoading,

isTemplate) {

var showVIP = function() {

g_form.showFieldMsg('x_53167_hotel1_check_in.guest','Guest is a VIP');

};

if (isLoading) {

if(g_scratchpad.vip'){

showVIP();

}

return;

}else{

g_form.hideFieldMsg('x_53167_hotel1_check_in.guest');

}

if(newValue==''){

return;

}

6. The logs dont seem to have any error captured

22:42:32.622: App:Hotel1 ==> 'Get VIP flag' on x_53167_hotel1_check_in:CHE0001128

22:42:32.623: >> Entering scope [x_53167_hotel1]

22:42:32.623: << Exited scope [x_53167_hotel1], popped back into [rhino.global]

22:42:32.623: App:Hotel1 <== 'Get VIP flag' on x_53167_hotel1_check_in:CHE0001128

22:42:32.623: Finished executing before_display before business rules on x_53167_hotel1_check_in:CHE0001128

Please help. Thanks a lot.

Hi Vivek,

I think you need to do GlideAjax, as per my understanding Business Rule get trigger when form loads or you save the record. When you will do onChange then at time there is no action happening on form. I tried below code and it works fine, please check if this helps.

onChange Client Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

var sys_id = newValue;

var userDetails = new GlideAjax("DisplayUserDetails");

userDetails.addParam("sysparm_name", "getUserDetails");

userDetails.addParam("sysparm_sys_id", sys_id);

userDetails.getXML(ajaxResponse);

function ajaxResponse(serverResponse) {

var answer = serverResponse.responseXML.documentElement.getAttribute("answer");

if(answer == 'true')

g_form.showFieldMsg('caller_id', 'User is a VIP');

else

g_form.showFieldMsg('caller_id', 'User is NOT VIP');

}

Script Include:

var DisplayUserDetails = Class.create();

DisplayUserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getUserDetails : function() {

var sysid = this.getParameter('sysparm_sys_id');

var newUserRecord = new GlideRecord('sys_user');

newUserRecord.addQuery('sys_id', sysid);

newUserRecord.query();

if(newUserRecord.next())

{

var guestIsVIP = (newUserRecord.vip) ? true : false;

return guestIsVIP;

}

},

type: 'DisplayUserDetails'

});

x_53167_hotel1_guest >> is this reference type of field?

Hi Vivek,

i tried at my end and it's working. may be you are missing something. if you are working on your personal development instance then i can look into your script.

Check the above screenshot and it's working at my end and i can see the output in log.

sure. ServiceNow . There is an application called Hotel1 and you would see checkin and Guest tables under it. Thanks a lot.
