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)??

ECM Navigator allows navigate using CMIS protocol between Liferay and ECM Software like Alfresco or Nuxeo. Also you can create folders, upload and preview files or delete content from your repository. So you will be able to pusblish your repository with your favourite portal solution. The document library is a great tool to do it, but the performance is bad when the repository is big; so I invite you to try it and you check what I'm talking about you.

Features:
* CMIS configuration
* Explorer folder and files from repository
* Create and delete folders
* Upload, upgrade and delete files
* Permisions configuration by entry
* Files Previews (office, text, images, videos)
* Open files in LibreOffice or OpenOffice
* Download files from repository into local drive
* See versions of a file entry
* Full ajax navigator
