CakePHP unlockedFields error

[244863]

Here is the code for my view:

<div class="column span-24">
	<div class="box">
		<?php
			echo $this->html->tag('h2', $title_for_layout);
			echo $this->form->create('DocumentationDocument', array('action' => 'add', 'type' => 'file'));
			
			echo $this->form->inputs(array(
				'File' => array(
					'type' => 'file',
					'label' => __('Local File', true),
					'required' => true
				),
				'site_id' => array(
					'type' => 'hidden'
				),
				'site_name' => array(
					'class' => 'site_name span-8',
					'type' => 'text',
					'required' => true,
					'between' => $this->html->tag(
						'div',
						$this->html->para('notice', __('Begin typing the site name and choose from the resultant list.', true)),
						array('class' => 'field-description')
					)
				),
				'documentation_category_id' => array(
					'empty' => '...',
					'class' => 'span-8',
					'required' => true
				),
				'asset_category_id' => array(
					'empty' => '...',
					'class' => 'span-8',
					'required' => true
				),
				'date_produced' => array('type' => 'date')
			));
			
			echo $this->html->para('notice', sprintf("Maximum file size: $size_limit"));
			
			echo $this->element('standard-form-buttons');
		?>
	</div>
</div>
<?php
	echo $this->element('sites', array(), array('cache' => true));
	
	echo $this->html->scriptBlock('
		$(function() {
			$(".site_name").autocomplete(sites, {
				dataType: "json",
				matchContains: true,
				mustMatch: true,
				parse: function(data) {
					return $.map(data, function(row) {
						return {
							data: row,
							value: row.display_name,
							result: row.display_name
						}
					});
				},
				formatItem: function(item) {
					return item.display_name;
				},
				formatResult: function(item) {
					return item.display_name;
				}
			}).result(function(event, data, formatted) {
				if (data && data.id) {
					allSites = $(".site", $("#sites"));
					index = allSites.index($(this).closest(".site"));
					$("#DocumentationDocumentSiteId").val(data.id);
					$(this).siblings(".error-message").hide(100).parent().removeClass("error");
				}
			});
		});
	', array('inline' => false));

	$this->Form->unlockField('DocumentationDocument.site_id');
	echo $this->form->end();
?>

If I remove the following line of JS the page posts fine:

 

$("#DocumentationDocumentSiteId").val(data.id);

 

I am pretty sure I have the unlockedField line correct as it works on other pages.

 

Any ideas as to why it won't post?

 

Thanks,

Hi,

 

Tried this in my app controller's before filter:

 

        $this->Security->unlockFields = array('DocumentationDocument.site_id');

still does not work, unless I uncomment that line of code???
