Hi,
I have just upgraded my projects dependencies under maven from T5.0.11
to T5.0.13. Everything compiled OK (after I changed all the *.tapestry.*
imports to *.tapestry5.* imports and used the new refactored constants
classes). However when I request a page that includes a BeanEditForm I
get a large stack trace that seems to be caused by the following : -

I had a look at the documentation of tapestry logging. I followed the
instructions here
http://tapestry.apache.org/tapestry5/tapestry-ioc/logging.html and added
the exclusions for log4j and added a dependency for logback (which we
use instead of log4j) (actually they were already in place, since this
worked fine in T5.0.11). And yet I get the problem above. I know this is
not specifically a Tapestry 5 issue but it is a new issue with T5.0.13
that was not present in T5.0.11 which worked fine with this
configuration. Any ideas anyone? Looking at the maven dependency tree
everything that needs to be there seems to be (logback, slf4j-apiare
there and log4j and slf4j-log4j12 are not)
Hope you can help,
Russell
