Symptoms

Catalog UI policies do not work when variable sets have the same name as the variable.

Release

London

Cause

The Internal name for Variable Sets has been added in the London release, it should not have the same name as any Variable associated to that set.

Resolution

Change the Internal name of the Variable set to something other than its variable name.

Script to find affected variables:

var variables = new GlideRecord('item_option_new');
variables.query();
while(variables.next()) {
  var varSet = variables.getValue('variable_set');
  var varName = variables.getValue('name');
  if (!varSet)
    continue;
  else {
    var varSetGr = new GlideRecord('item_option_new_set');
    varSetGr.addQuery('sys_id', varSet);
    varSetGr.query();
    if (varSetGr.next())
    if (varSetGr.getValue('internal_name') === variables.getValue('name'))
    gs.print('Variable name and Internal name of the variable set are the same for ' + varName);
  }
}
