Hi Tuomo:
There is another attribute that can help you:
as="string" (default) - returns the value of the given path as a String.
as="object" returns the value of the given path as an Object
(org.w3c.dom.DocumentFragment).
as="xml" returns the value of the given path as an
org.w3c.dom.DocumentFragment. The root of the DocumentFragment is
<xsp-session-fw:xml>.
Are you tried this attribute? Maybe it can helps you.
The idea of the default as="string" is to let you add easily inside your
XSP some strings. We are using to show the user name in a welcome page.
Example:
<p>Hi <xsp-session-fw:getxml context="authentication"
path="/authentication/data/full_name"/>, welcome back to the System</p>
Of course in this example the @path always exists, so we don't need to
test if the @path exists in the given session context.
So, I recommend you use as="object", get the object and if the object is
null, then there is nothing. Else the path exists so you can get the
string.
Please comment if this works for you. I am not sure if this will work,
since Carsten did changes in the Helperclass in order to helps you.
Best Regards,
Antonio Gallardo.
