[xsp-session-fw] NPE when use getxml with empty tag

Hi
>From the portal engine, for example, when I use <xsp-session-fw:getxml
as="string" context="authentication" path="/authentication/data/title"/> I
got an NPE if this tag is empty.
If I put something on it in the sunrise-user.xml from the portal sample,
it's working fine.
Any idea?

I have the following problem with the solution you suggested. I use the
getxml inside a <xsp:expr>:

<xsp:expr>Integer.parseInt(<xsp-session-fw:getxml context="authentication"
path="/authentication/data/loc_id" as="string"/>)</xsp:expr>

This is translated to:

(Integer.parseInt(
        	node = ((DocumentFragment)(XSPSessionFwHelper.getXML(this.manager,
                String.valueOf("authentication"),
                String.valueOf("/authentication/data/loc_id")))).getFirstChild();
        	node != null ? node.getNodeValue() : ""))

In this sample this is a bad compiled code, because we cannot use inside a
function Integer.parseInt 2 instructions:

(DocumentFragment)(XSPSessionFwHelper.getXML(this.manager,
                String.valueOf("authentication"),
                String.valueOf("/authentication/data/loc_id")))).getFirstChild();

and

node != null ? node.getNodeValue() : ""

What we can do?

as="object"
