Polymer reset parameters format not working
问题 I am new to Polymer 2.0. I need to update a field called Print Name to set the values I put in First Name + Last Name. Currently I get a version of it that is not working as I get bad request. 'System.FormatException: Input string was not in a correct format.' _updateField(e) { e.preventDefault(); this.set('_contract.signeeContact.printName', [this._contract.signeeContact.firstName, this._contract.signeeContact.lastName]); // printName: ["firstName", "LastName"] // this is not correct it
