Code Block

theme	Eclipse
linenumbers	true

const record = new SimpleRecord new SimpleRecord('task');
record.get('159644860216948298', () => {
  console    console.log(record.number);  // TSK0000123
});

Dot-walking is not available for fields of the Reference type. You can use a the callback function sequence as a workaround.
For example, instead of server-side dot-walking:

Code Block

language	js
theme	Eclipse

current.slm_commitmentcaller.agreementcompany.service_idphone

in client-side script, it will be looks look like:

Code Block

language	js
theme	Eclipse
linenumbers	true

let callersCompanyPhone = '';
if (commitmentIDcallerID) {
    const commitmentuser = new SimpleRecord('slm_commitmentuser');
    commitmentuser.get(commitmentIDcallerID, () => {
        const agreementcompany = new SimpleRecord('agreementorg_company');
        agreementcompany.get(commitmentuser.agreementcompany, () => {
         const service = new SimpleRecord('sys_cmdb_ci_service');if (company.next()) {
