I'm using OpenERp POS 7 latest version. I need help for create a product under specific categary.

Use Case: I like tto create a new categary and create a product for that new categary.

Steps Followed:

Step 1: I create a Categary  from "Point Of Sale" -> "Products" -> "Product Categary" -> "Create"

Steps 2: When I create a product from "Point Of Sale" -> "Products" -> "Product" -> "Create", I'm not seeing the already created categary in step 1. In Product creation screen again we can create a new categary but categary created from product screen in not displayed in sales screen

Also I obseve that in Odoo pos demo I can see the categary labeled as  "Pos/Public Product Categories" instead of "Product Categary" is there any difference in these?
