Display Variable Editor in Service Portal

[reginabautista]

Hi guys,

I have followed the workaround in the article in HI below...

ServiceNow KB: In Service Portal, the Variable Editor widget does not work with sc_task records and ...

I have then cloned the sp-variable-editor and embed it to the the Form cloned widget.

However the variables are still not displaying on the form.

Would you know what am I doing wrong?

Hi guys I have debugged the server script, the reason the variables were not displaying is because I was viewing a record created from a record producer. I had to change the code to get the record producer sysid rather than the catalog item:

var gr = new GlideRecord(data.table);

    if (gr.get(data.sys_id)) {

          var recordClassName = gr.getRecordClassName();

console.log('recordClassNamee=' +   recordClassName);

          if (recordClassName != data.table) {

                data.table = recordClassName

                gr = new GlideRecord(data.table);

                gr.get($sp.getParameter("sys_id"));

console.log('sysid=' + $sp.getParameter("sys_id"));

                }

          try {

            //var catItem = data.table == "sc_task" ? gr.request_item.cat_item : gr.cat_item;

var catItem = gr.u_record_producer;

console.log('gr.cat_item=' + gr.cat_item);

// data.sc_cat_item = $sp.getCatalogItem(catItem);

//regina added params to the getCAtalogItem as these were introduced after Istanbul 3a+

//catItem = '13ffd3dddbd28b40f82ada94ce9619e3';

data.sc_cat_item = $sp.getCatalogItem(catItem,false);

Hi Regina,

Thank you very much for the solution it worked very well. It worked for me - I just wanted to clarify how it worked:.

1. The formatter which displays the variables is located on the sp_ui_formatter table with a formatter of com_glideapp_servicecatalog_veditor

2. The fix you provided needs to be applied to the widget this formatter points to. Essentially var catItem variable needs to have the sys_id of the record producer in this case. This can be made to work with multiple tables if needed using if conditions for example:

if(data.table == "u_custom_table_1"){//So that variables can be displayed for the custom table you can have multiple if conditions for difference tables

var catItem = gr.u_cat_item; //A reference to the record producer the record is created from

  }

  else{

  var catItem = data.table == "sc_task" ? gr.request_item.cat_item : gr.cat_item;

  }

Hi there, I am on a Kingston instance and I am unable to get this working... I may be misunderstanding exactly what you had done. Could you please provide me with your updated code for the cloned sp-variable-editor widget?
