Hello all!
In my frame based solution I have a main frame with the navigation being
some links to xhtml files for the second frame. For each of these links I
did a sitemap in a sub-directory.
The phaenomenon I realised:
When I click on a navigation link for the first time everything seems ok.
When clicking for the second time I get an exception from source Cocoon
servlet(see attached file) which I cannot explain why. Furthermore I have to
restart my JRUN4 server again to get everything working (but again only once
the chance to click a navigation link :-(
Unfortunately it may happen that the above phaenomenon does not appear
without any changes(but only with a 1% chance when starting the JRUN server
new, I guess).
The main sitemap contains:
--------------------------
<snip>
<map:match pattern="users/*">
<map:mount check-reload="no" uri-prefix="users" src="users/"/>
</map:match>
</snip>
Using no sub-directories and therefore a differently named sub-sitemap seems
to work more stable but does not provide the structured solution like I want
it.
Is this a known bug? Some ideas what I should check?
Thanks, Kurt
