Problems with logic:iterate

[Gekka <ge...@bluezone.no>]

Hi,

I'm using Struts 1.1b2 and Tomcat 4.1.12 on Windows 2000 and I have some
problems with the logic iterate tag. What I do is that I set a
Collection (HashSet) in the request object inside execute() in an action
and then pass control to a jsp to iterate over the results. Here's what
I do in the jsp:

<logic:iterate id="menuElement" name="items" scope="request"
type="bean.HTMLLink">
	<html:link href="<bean:write name="menuElement" property="url"/>">
		<bean:write name="menuElement" property="caption"/>
	</html:link>
</logic:iterate>

When I hit this code Tomcat tells me:

org.apache.jasper.JasperException: /menu.jsp(6,47)

I have tried <logic:present name="items" scope="request">Hello
Items..</logic:present> to make sure that 'items' is present in the
request object and it is. Anyone know what to do?
