[oscarinak]

Bug report

The following problem occurs in the ADempiere-Vue point of sale where when adding a product either from the search panel or from the catalog option, it is slow to associate the order, just as it is slow to be able to delete a product.

Steps to reproduce

In order to verify this case, the following steps must be applied:

1.Enter the point of sale, either "USD" or "VES"
2.Associate business partner "Customer"
3. Search for a product from the "Search" panel
4. Check a product from the "Product Catalog"
5. Select one of the products that were added to the order and delete it
