Empty List collector ?

[sandaru]

Hi,

I'm in a need of creating an empty list collector. Since we cannot initiate an empty list controller, what i'm going to do is run an onLoad script to remove all the elements from the List collector and add it manually via   a script.

Can i do this ? and how to do that ?

All the way i searched i only found some thing called "move" which moves elements from left to right and vise versa.

Thank you.

Here is how you can do it. You will have use filter string sys_id=''; This will load you with empty list collector

function onLoad() {

    //Apply a default filter to the list collector variable

    var collectorName = 'configuration_items';

    var filterString = 'sys_id='+'';

    //Hide the list collector until we've set the filter

    g_form.setDisplay(collectorName, false);

    setCollectorFilter();

    function setCollectorFilter(){

          //Test if the g_filter property is defined on our list collector.

          //If it hasn't rendered yet, wait 100ms and try again.

          if(typeof(window[collectorName + 'g_filter']) == 'undefined'){

                setTimeout(setCollectorFilter, 100);

                return;

          }

          //Find the filter elements

          var fil = gel('ep');

          //Hide the filter elements by un-commenting the following lines

          /*fil.rows[0].style.display = 'none';

          fil.rows[1].style.display = 'none';

          fil.nextSibling.rows[0].style.display = 'none'; //Filter description text*/

          //Reset the filter query

          window[collectorName + 'g_filter'].reset();

          window[collectorName + 'g_filter'].setQuery(filterString);

          window[collectorName + 'acRequest'](null);

          //Redisplay the list collector variable

          g_form.setDisplay(collectorName, true);

    }

}

Most simpler way to remove all the options from list collector. Add these 3 lines in your onLoad client script

var varName = 'YOUR_VARIABLE_NAME_HERE';

var leftBucket = gel(varName + '_select_0');

var rightBucket = gel(varName + '_select_1');

rightBucket.options.length=0;

leftBucket.options.length=0;
