Notes: After logout, authentication is no longer possible

Symptoms:

User presses the login button/link, inserts username and password and gets authenticated. Later he presses the logout button/link, and he is successfully logged out. If he tries to login again, he's unable to because the authentication form is never presented again (unless he closes the browser window and re-opens it).

Possible Solution:

In case the login link is like this:

top.location.href = "/database_path?OpenDatabase&Login">

change it to:

top.location.href = "/database_path?Login&redirectTo=database_path?OpenDatabase">

Notes: View doesn't refresh

Symptoms:

permanently shows the Refresh Icon

the "NoCache" parameter on the dblookup "doesn't work"

the view.Refresh statement doesn't refresh the view

Problem:

The view probably uses @Now or @Today formulas in the Selection Formula or in a column, which prevents the view's index to be updated (it's always out-of-date as these formulas force the calculation to go to the minute:second detail).

Solution:

Use this formula instead: @TextToTime("Today") - it calculates only to the year-month-day so that the index only updates once a day.
