Liferay's Calendar app allows users and organizations to create, track, share, and manage events. In addition, the Calendar app supports notifications, integration with Social Office, and staging. As a user, you can create as many calendars as you need. As an administrator, you are able to manage the scheduling of Calendar Resources such as rooms and projectors. All content from the old Calendar portlet is automatically imported into this new application.
In Liferay 7.1, this app is installed by default and updated through Liferay DXP Fix Packs and Liferay Portal CE GA releases. Using Liferay Marketplace to update the app on Liferay 7.1 will cause an error.
The following has evaluated to null or missing:
==> channel.items [in template "3192443#3192485#null" at line 18, column 30]
----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
