[C2] Session validator deletes {1}
It looks like there is a bug in SessionValidatorAction. Suppose you have
a sitemap entry like this one:
<map:match pattern="*.html">
<map:act type="session-validator">
<map:parameter name="descriptor" context://descriptors/params.xml"/>
<map:parameter name="validate" value="username"/>
<map:generate type="serverpages" src="docs/{1}.xsp"/>
<map:transform src="stylesheets/simple-page2html.xsl"/>
<map:serialize/>
</map:act>
<map:redirect-to uri="login.html"/>
</map:match>
This fails because the XSP generator cannot find "docs/null.xsp".
Apparently the SessionValidatorAction deletes any exixting sitemap
parameter before copying the session attributes to the sitemap, so the
value of {1} is lost.
Can anyone confirm this?

Beautiful! It works perfectly now, thank you.

In this case, you get to experience the heirarchy of matchers. Try the following:
<map:match pattern="*.html">
<map:act type="session-validator">
<map:parameter name="descriptor" context://descriptors/params.xml"/>
<map:parameter name="validate" value="username"/>
<map:generate type="serverpages" src="docs/{../1}.xsp"/>
<map:transform src="stylesheets/simple-page2html.xsl"/>
<map:serialize/>
</map:act>
<map:redirect-to uri="login.html"/>
</map:match>
Please note that {1} is changed to {../1}. This is due to the fact that matchers
and Actions can nest inside each other, and return values that can be acted upon
in the sitemap.
Concider the following example:
<map:match pattern="**.html">
<map:match pattern="inbox/**.html">
<map:generator type="serverpages" src="{1}.xsp"/>
</map:match>
</map:match>
What does {1} match? The way it is defined in the sitemap, is that there is
a heirarchy. If we wanted to match the original wildcard, you would have to
reference it like this: {../1}. If you want to match the internal wildcard,
you already have it specified correctly.

Your sitemap is wrong (not the system). You have the following stack of
Maps. On top is the one from the Matcher and next comes the one from the
Action. Thus your reference to the matchers value should be {../1}
