We are trying to make something like consumables management (yes, we know that this feature is in roadmap, but we need it NOW).

Added custom product type:

Cartridges (type -- Component)

Trying to add Cartridge via /BarcodeScanAction.do?method=vendorBarcode

Selecting Product type -- Cartridge

Adding new product type (by Cartridge name)

Adding barcode -- everything is ok.

But after pressing "Add assets" nothing happens. If we change Product type everything works as expected.
