geoff,
you're right! i moved the create-session attribute to the first map:part in
the aggregation you saw in my example. i did the same in another nearly
identical aggregation in my sitemap. now i'm able to access the session
from within the particular map:part where i wanted to in the first place.
i don't quite understand why this change made it work, though. my only
clues are:
1.) by accessing the session in the first map:part, i've somehow enabled
session access in a later map:part that otherwise wouldn't have
been able to access the session successfully.
2.) the IllegalStateException was telling me that i "Cannot create a
session
after the response has been committed."
each map:part invokes a matcher similar to this one:
<map:match pattern="choose_item.products">
<map:generate type="serverpages" src="xsp/choose_item.products.xsp"/>
<map:serialize type="xml"/>
</map:match>
does the map:serialize "commit" the response? is that what the error
message is
talking about?
thanks!
Mike Lenyon
