Need to set Label of Field based on Task Type

[Shane J]

I need to set that label for 'Task' (for Time Cards in this case) to the Task Type of the record within the field.

function onCondition() {

    var task1 = g_form.getReference('task');

        g_form.setLabelOf('task', task1.getTableName());

}

This nets me 'task' for the label, I suppose it is the task table, but not what I want.   So I tried this:

function onCondition() {

    var task1 = g_form.getReference('task');

g_form.setLabelOf('task', task1.sys_class_name);

}

This nets me (for example) 'pm_project' for a Project.   I'd like to build this so I don't have to setup every possible option for types of records we could have in there in a way that doesn't look goofy to the User, thus why I want the table name.

I think we're crossing wires.   I should be able to pass the task.sys_class_name as a parameter to the Script Includes via the Client Script, then use that parameter to query the sys_db_object table in the Script Includes to get the Label from there and return it as an 'answer' - right?

I realize now that the entire reason you have me doing two queries is to avoid getReference.

I don't know of any way to get the table name of the reference field directly on the form.

CS:

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

  if (isLoading || newValue === '') {

  return;

  }

  var ga = new GlideAjax('TaskLabelUpdate');

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

  ga.addParam('task_id', newValue);

  ga.getXML(doAlert);

}

// Callback function to process the response returned from the server

function doAlert(response) {

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

  g_form.setLabelOf('task', answer);

}

Script Includes, set to 'Client Callable':

var TaskLabelUpdate = Class.create();

TaskLabelUpdate.prototype = Object.extendsObject(AbstractAjaxProcessor, {

  getTaskLabel: function() {

  var taskID = this.getParameter('task_id');

  var tn = new GlideRecord ('task');

  tn.addQuery('sys_id', taskID);

  tn.query();

  while (tn.next()){

  var thename = tn.sys_class_name;

  alert(thename);

  var tab = new GlideRecord('sys_db_object');

  tab.addQuery('name', thename);

  tab.query();

  while (tab.next()){

  var retVal = tab.label;

  return retVal;

  }

  }

  },

      type: 'TaskLabelUpdate'});

Still getting 'null' and losing my mind.   I know my query is sound because I setup a BR to verify that's working.

Try removing this line from your script include: alert(thename);

It might be erroring out since that's a client-side function and you're trying to run it server-side.
