Hi all,
having a curious problem with the StrutsLinkTool.
Using <a href="$link.setForward("putObjectInSession")">Put Object In Session</a>
I get an error returned as at the end of this email.
However, I used the JSP equivalent for sanity purposes and it works just fine.
<html:link forward="putObjectInSession">putObjectInSession</html:link>
Does anyone have any ideas? Many thanks in advance..
Robin
