Negotiation CorDapp Missing a Time-window

[adelrustum]

• In the Negotiation CorDapp both ProposalState and TradeState belong to the same contract ProposalAndTradeContract.
• Inside the contract, it mandates for Propose command that there should be a time-window (see here).
• But proposalFlow (which uses Propose command for the transaction) doesn't add a time-window; so the transaction verification would definitely fail (see here).
• Btw, the above mentioned flow doesn't call tx.verify() before signing the transaction (see here).

Update: AcceptanceFlow and ModificationFlow don't add a time-window either; even though it's required by the contract.
