Subject Re: No SesionManager provided for Seleector?

It should normaly be created only once on the first page request. At the
moment for test purposes there is the following pipe:

<map:match pattern="sessiontest">
 <map:generate src="foo.xml"/>
 <map:transform type="session"/>
 <map:select type="context">
   ...
 </map:select>
 <map:serialize type="xml"/>
</map:match>

So it is created by the session transformer before the select state.

I have now commented out the session create statement.. But nothing changes.

Cheers,
Jan
