Pages app not saving widgets

[CalvinK]

Hi everyone.

I created a new page and selected manual HTML.

I am using the following code only in the page:

<h1 class='ipsType_pageTitle'>Title</h1>
<p class='ipsType_minorHeading'>Heading</p>
<br />
<div>
	<div class='ipsGrid ipsGrid_collapsePhone'>
		<div class='ipsGrid_span2'>
			{template="widgetContainer" group="pages" app="cms" params="'col1', $widgets, 'vertical'"}
		</div>
		<div class='ipsGrid_span2'>
			{template="widgetContainer" group="pages" app="cms" params="'col2', $widgets, 'vertical'"}
		</div>
		<div class='ipsGrid_span5'>
			{template="widgetContainer" group="pages" app="cms" params="'col3', $widgets, 'vertical'"}
		</div>
      <div class='ipsGrid_span3'>
			{template="widgetContainer" group="pages" app="cms" params="'col4', $widgets, 'vertical'"}
		</div>
	</div>
</div>

The only problem is that when I then go to add the widgets on, a page refresh deletes everything!

I'm not quite sure what is happening here or why it is doing it. Any help?
