Liferay Components for Talend™
处理模板时发生错误。 
The following has evaluated to null or missing:
==> channel.items  [in template "3192443#3192485#null" at line 109, 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)??

If you use Talend Open Studio for data integration jobs, Liferay’s Talend Components make it easier to import/export data between Liferay DXP/Portal and other external systems (eg. MySQL, SAP, Salesforce). As of 7.4.x, these components are part of the Liferay DXP/Portal codebase and must be built and added into Talend Open Studio. Once added, you can use these components to design Talend Jobs that connect to Liferay and perform ETL operations along with other Talend components.

Liferay’s Talend Components can connect to both out-of-the-box Headless APIs and any custom APIs developed using REST Builder. All components require a defined Headless API endpoint. Each endpoint path must begin with /headless- (e.g.,/headless-delivery-api) and include a proper version sub-path (e.g.,/headless-commerce-admin-catalog/v1.0, /headless-commerce-delivery-catalog/v1.0).

NOTE: Liferay’s Talend Components are not officially supported. Please use at your own discretion.

Talend Open Studio is a prerequisite for using the Liferay components and a trial version is free to download. See here for full pricing details.
