Comment 2 Vladimir Kvashin 2011-04-05 13:14:55 UTC 
The issue is in wrong equals() method:
according to the debugger,
the following two file objects return equals() == true
vk@enif:22:/export/home4/vk/LINK-TO-SSSIDE-VK/test-code/link-to-test_io_net
vk@enif:22:/export/home4/vk/LINK-TO-SSSIDE-VK/test-code/test_io_net/test_io.c

That's because RemoteChildLink class has null cache file, and equals() compares cache files => null == null and it returns true
Comment 3 Vladimir Kvashin 2011-04-05 13:48:54 UTC 
This makes working with full remote project that contain a symlink or reside in symlink impossible.
Comment 4 Vladimir Kvashin 2011-04-05 14:28:23 UTC 
fixed in cnd-main:

Log: fixed #197437 - IllegalArgumentException: Not a DataFolder
Comment 6 Alexander Pepin 2011-04-06 12:59:57 UTC 
Verified in trunk.
The fix causes synchronizing problem with an exception in IDE log and it will be filed separately.
Comment 7 Vladimir Kvashin 2011-06-02 09:05:04 UTC 
I've just double checked, fix exists both in trunk and in release701.
