Is it possible remove the default value set on a List_Box? I have created a script that populates a list box from field values within a form but need to unselect the default value.

Here is a snippet of the code:

var a = this.getField("ESD_K_1").value;
var b = this.getField("ESD_K_2").value;
var c = this.getField("ESD_K_3").value;

var n = new Object();
n[a]=1;
n[b]=2;
n

=3;
 
var myDialog = 
 
{
initialize: function(dialog)
{
  dialog.load({"sub1":n});
 
 },
 
Thanks in advance for your help.

the selected item in a custom dialog list is indicated by a positive number. You've set all you entries to be positive. This is incorrect. Only set one to a positive number, or if you don't want any selection make them all negative.

Like this:

var n = {};
n[a]=-1;
n[b]=-2;
n
=-3; This will create a list with no selections.

Unfortunately Adobe did not do a full list box implementation when they added custom dialogs (the JSADM) to Acrobat. It's missing many common list box features. Items in a custom dialog list box are sorted lexically. I would have been better to do no sorting at all. That way we could at least arrange things the way we'd like. But, there are no other options.

However, you can make use of this default sorting by prefixing entries with numbers or letters. It looks a bit ugly but I do month lists this way (01:January, 02:Febuary, etc.) The colon ":" is necessary so that the item data can be parsed out.
