URL not active in UWL

I'm trying to pass a URL from a workflow container to a task in the UWL. I can display the URL when I open the task, but the URL is not active. I cannot click on the link. Any suggestions?

This is the code that I'm using in my XML file:

<DisplayAttribute name="TEST_URL" type="link" sortable="no" maxTextWidth="0" headerVisible="yes" actionRef="ChangeUrl">

<Descriptions default="Test URL"/>

</DisplayAttribute>

The ChangeUrl action looks like this:

<Action name="ChangeUrl" handler="UrlLauncher" launchInNewWindow="yes">

<Properties>

<Property name="url" value="${item.TEST_URL}"/>

</Properties>

<Descriptions default="Test URL"/>

</Action>

Your assistance is appreciated,

Keith
