> Hi wicketeers!
> When calling newFormTester("form") I found out that the page's model is left
> in an attached state after the call. The constructor
> protected FormTester(final String path, final Form<?> workingForm,
> final BaseWicketTester wicketTester, final boolean
> fillBlankString)
> is accessing the form component hierarchy and it's models (therefore
> attaches it) but never call's detach so this is the situation:
> ** all models is detached
> final FormTester form = tester.newFormTester("form");
> ** one or more component models are now attached !!!
> having the model(s) already attached / loaded before calling form.submit() is
> a problem!
> - I override Form.process() to start a new transaction (similar to Igor's
> EntityModel: http://wicketinaction.com/2008/09/building-a-smart-entitymodel)
> - During form processing the entity model will get modified
> - After form processing the transaction is committed and the changes are
> flushed to the database
> However, when the entity get's loaded before form processing starts this
> doesn't work anymore. Hibernate thinks the entity is transient (it was loaded
> in a different session and *btw* I don't use session in view).
> When running the same testcase with jetty and a browser it works just fine.
> I think FormTester's constructor should call detach to clean up the model
> state before returning a new FormTester.
