I've just uploaded version 0.2.3 of the Indicia Warehouse and Client Helpers code to the downloads page at http://code.google.com/p/indicia/downloads/list.

Mostly this is a bugfix release with quite a few tweaks and improvements, but here is a summary of the main changes:
1) Issue 151. Some fixes to pagination and sorting bugs that occurred in the grids on the Warehouse.
2) Samples  can now have a parent-child hierarchy.
3) Improved HTML output with respect to producing valid HTML from the client helper library.
4) The default install now includes additional custom attributes for you to re-use.
5) Issue 168 - uploading terms as csv file bug fixes.
6) Issue 169 - records save correctly with no map control.
7) Problems on Unix/Linux installations of the warehouse when posting Warehouse records fixed.
8) Issue 172 - after saving a new record with validation errors, the Delete button does not appear unnecessarily.

Best Wishes
