Close Or Disable Alert Message on Liferay 7 - notifications

Question

How do I remove or disable the alert message that appears above right the page when request/response takes too long or the user session is ending?
I added the ff JavaScript inside AUI().ready(){} in main.js file of the theme;
$('.lfr-alert-container .close, .lfr-notification-container .close').click(function() {
$(this).parent().parent().addClass('hidden');
});
But this code only works to my custom SessionMessages/SessionErrors. The alert message does not respond.
Any help will be appreciated. Thanks.

Answer 1

Please add following to portal-ext.properties :
session.timeout.warning=0
session.timeout.redirect.on.expire=true

Answer 2

You can set the following property to false in your portal-ext.properties:
#
# Set this to true to enable Single Page Application links.
#
javascript.single.page.application.enabled=false
I know that the property name is a little bit confusing, but it will turn off the mentioned message and won't try to submit everything as AJAX.
Another option is to change the timeout:
#
# Set the timeout in milliseconds before SPA navigation times out and falls
# back to standard navigation.
#
javascript.single.page.application.timeout=0
The session is ending message is something different, which you can turn of with the following property:
#
# Specify the number of minutes before a warning is sent to the user
# informing the user of the session expiration. Specify 0 to disable any
# warnings.
#
session.timeout.warning=0
It helps to study /liferay-src/portal-impl/src/portal.properties, where you will find all options that you can configure with your portal-ext.properties. In addition since Liferay 7 some options are now configured with files in liferay/osgi/configs - if you look for classes annotated with #ExtendedObjectClassDefinition you should get an idea.
