I want to be able to select multiple items from the siteTree, so i could say asssign a banner to multiple pages.

map() doesn't seem to work anyone know of another way.
[warning] array_keys() expects parameter 1 to be array object given
error line 138 ListboxField.php

line 138 = $hasCommas ....

i did try explode but that doesn't seem to solve

why does map(0 work with checkboxes but not listbox

Checkbox works

    $SiteTreeIDs = SiteTree::get();
    if (!empty($SiteTreeIDs)) {
    $map = $SiteTreeIDs->map('ID', 'Title');
    new CheckboxSetField(
    $name = "selectedPagesFld",
    $title = "Select Pages",
    $source = $map

ListboxField doesn't

$SiteTreeIDs = SiteTree::get();
if (!empty($SiteTreeIDs)) {
    $treemap = $SiteTreeIDs->map('ID', 'Title');
    $mylistboxfield = new ListboxField(
"Select Pages",
$source = $treemap,
    $value = ""
    /* */

return $fields;
