problem with urlInvoke

Hi all,
I'm new to Canoo, and I'm stuck to a problem with urlInvoke

I use storeXPath to store a url, and I make something like

			<storeXPath description="Extract link"
			            xpath="//a[@title='Ryanair.com']/@href"
			            property="myurl" />
			
			<invoke url="${mybaseurl}#{myurl}" 
				description="call preview" />

the problem is that, even if in test report I see the correct url, the url called doesn't have the #{myurl} part: it seems that the url invoked is only ${mybaseurl}

Am I doing anything wrong?
I'm using the latest snapshot.

Thanks in advance
Enrico
