re/store context somehow?

Hi there, my client made a somewhat weird request: wants me to store “the last context the user worked in” in his session, and restore it when the user comes to the application through a specific Direct Action (and the session still lives). In other words, suppose the user works in the app for

enumerating sessions?

Hi there, is there a way to enumerate sessions which are alive inside of a WO/ERXApplication? I guess I can create such a list myself, adding new ones in session.awake, keeping it weak not to prevent old sessions to be destroyed (or perhaps storing just session IDs), yadda yadda, but it would

Hi there, pretty rarely, but alas repeatedly — something like, twice a year — our clients observe a weird behaviour that - they add “a row to a table”, means an eo into a standard 1:N relationship; - immediately after that, they do not see the newly added row in the GUI, nor do see it newly
