bug #7047
Vaadin UI and View scope beans are not always destroyed correctly
100%
Description
while examining problems related to the connection pool runnig out of available connections it turned out that Vaadin UI and View scope beans are not always destroyed correctly once the view or UI was no longer used.
One problem was caused by the LoginViewBean being in UIScope. This issue has been solved meanwhile with cdm-vaadin|157c9c3 but it seems as if some views and presenters are still never being disposed and garbage collected correctly. This can potentially cause the vaadin UIs to eat up all memory over long time.

The RegistrationWorkingsetPresenter, LoginPresenter and RegistationUI still are not destroyed correctly. At least RegistrationWorkingsetPresenter still seems to be registered to the view event bus.
Is this a session timeout issue?

if you think it is fixed shouldn't we set it to resolved and keep in 5.4 milestone? So we remember it as being primarily a review ticket. If not fully fixed we can still move it to next version, if fixed we simply close it.
