broken flow samples

[Tim Myers <ph...@pirouline.sts.jhu.edu>]

after copying the documentation directory into the webapp so that the samples
mostly work--

when accessing
http://localhost:8888/samples/flow/examples/calc/

i get "No pipeline matched request: samples/flow/examples/calc/getNumberA.html"

I would just chalk that up as a configuration error-- but

http://localhost:8888/samples/flow/examples/calc/getNumberA.html
works fine when accessed directly (i.e. not through the flow)

One thing to not is that the .html matcher is in the /flow/ sitemap,
not the /calc/ sitemap.

an excerpt from the exception:

FWD:org.mozilla.javascript.NativeObject
org.apache.cocoon.ResourceNotFoundException: No pipeline matched request: samples/flow/examples/calc/getNumberA.html

Notice that that there is no MountNode in the stack trace.  Is this fallout from
Carsten's recent environment cleanups?  I suspect that the wrong treeprocessor 
is being invoked.
