You can't achieve the 'symlink' functionality with multilocations in eZ if you have subtree objects on original locations. You can achieve it with custom classes which kind of redirect you to original location either using specified url or objectrelation attribute.
For example you can make a custom class with 2 attributes:
- name
- objectrelation
Then create that object in second location and connect it with original location over objectrelation attribute. Last thing to do is the full template for that class which only calls node_view_gui view=full for related object main node.
I created a SymLink content class with a title and a symlink (Object relation) attribute.
i created a full view for this class
{* symlink full view *}
<!-- spSymlink Full view -->
{node_view_gui view=full content_node=$node.object.data_map.symlink}
On display i got a "The maximum nesting level of 40 has been reached. The execution is stopped to avoid infinite recursion. " message instead of the full view of the object relation :(
