The 100,000 ft. answer is that trying to represent an account and its various options as a URL string is a broken concept and another deep design flaw in Camel. Change any option that results in a different URL string and Camel treats it as a completely new account, sets up all new cache storage for it, and doesn't even clean up the old cache. Camel needs to have some kind of account object onto which meta-data can be added and altered. But to actually answer your questions, CamelStores are loaded from EAccounts at startup in mail/e-mail-store.c:mail_store_load_accounts(). Once loaded, the CamelStore object is added to the EMFolderTreeStore, which serves as the model for the folder tree view in the side bar. EMFolderTreeStore responds to the "account-changed" signal by removing the CamelStore object associated with the changed EAccount, and loading a new one. I'm not exactly sure how that's handled within Camel, but my guess is this is the source of the problem. That's the only place I'm aware of that anything meaningful happens. The other "account-changed" handlers are for custom widgets that just list the accounts, like EAccountComboBox which appears in the composer. Hope this helps. _______________________________________________ evolution-hackers mailing list firstname.lastname@example.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers
