In the document list we do two call to load a folder:
1.Get the children
2.Get the current folder information
The second call could be avoided id the enhancement present in the https://issues.alfresco.com/jira/browse/REPO-1977 will be implemented.
If we use now the includeSource option in the children call it will not return the path for the current node also if it is present in the include information requested.
Without the path, the breadcrumbs stop to work correctly.
