I have a custom module wContracts with custom related module wCProducts.
There is a calculated contract_amount in wContracts which is the sum of product_amount for each product related to the contract in wCProducts
I need the currency to be editable.
Users can only add/edit product amount in the subpanel, they are not allowed to go to detail view on wCProducts.
And the contract amount is not editable because calculated.
I need them to be able to choose a currency to apply across the contract/products.
Any suggestions welcome.
