tapestry-hibernate and mysql console
Hi,
a T5 app uses tapestry-hibernate to display some pages, when I updated some
fields in mysql console, commit, and close the mysql console, and go back to
t5 app, some times the changes are not reflected, in fact, there are times
when I checked the mysql again, the data was still there, got some idea
what's wrong here? if this is not related to t5, sorry,
Angelo

you are right, unexpected behavior, it even writes back some value which I
set to null directly, of course this is for some testing app.

Hi Angelo
Yes this is not related to Tapestry. Hibernate caches the results for efficiency(there are different levels of caches involved) and so what you do directly with the database may not be updated in the cache for a while depending on the cache configuration.
My advice would be not to update directly when using hibernate as it can result in unexpected behavior.
regards
Taha
