Sebastian Staudt updated FREEMARKER-44:
---------------------------------------
Description:
I'm using Freemarker in a Spring web application and started to move to lazy
loaded Hibernate associations recently.
I noticed that Hibernate's infamous {{LazyInitializationException}} causes the
exception to be handled by the {{DispatcherServlet}}, leaving my
{{TemplateExceptionHandler}} unnoticed.
After digging a bit through Freemarker's code the reason seems to be that
default adapters like {{DefaultListAdapter}} do not handle exceptions e.g. when
calling {{list.size()}}.
IMHO, the default adapters should catch {{RuntimeException}} s inside their
methods and rethrow them wrapped into a {{TemplateException}}.
