Ubercart Products - Dimensions are required for custom packaging

When running a node import job for Ubercart Products (Ubercart version 6.x-2.0-rc6) there is a fatal import error for each item with the following text 'Dimensions are required for custom packaging'. This error is generated by the 'uc_ups_product_alter_validate' method in Ubercart shipping module 'uc_ups.module'. This error is generated when physical dimensions of a product are not specified.

The current implementation of the Ubercart Product import does have a mapping for product dimension i.e. length, width, and height. However, the values read from the import source are not being properly mapped so that when 'uc_ups_product_alter_validate' is executed the dimension values are all zero.

I do have a workaround. In the 'node_import' module you can update the file 'uc_product.inc' under folder 'supported/ubercart'. You must change the array's dimension keys to have a prefix of 'dim_'. For example, change $fields['length'] to $fields['dim_length']. This will allow the import to work properly. As a result of this change it seems that the import wizard will not automatically map columns named without the 'dim_' prefix to the appropriate dimension field. But of course you can do this manually.
