[ http://jira.andromda.org/browse/BPM-215?page=history ] Work on BPM-215 started by Wouter Zoons
> Support JavaBeans in action form > -------------------------------- > > Key: BPM-215 > URL: http://jira.andromda.org/browse/BPM-215 > Project: Bpm4Struts Cartridge > Type: Improvement > Versions: 3.1M1 > Reporter: Roland Szabo > Assignee: Wouter Zoons > Priority: Minor > Fix For: 3.1 > > It would be nice if the cartridge could utilize the nested property feature > of Struts. That would allow for the modeller to use JavaBeans as parameters > for controller methods, instead of listing every single property. The > controllers would have methods like: > +loadCustomer(customer : Customer) > This would mean that there is a Customer object in the generated form, called > customer. This would also simplify the implementation of the controller, as > most likely the Business Logic classes return a Customer object, or something > like that anyway, there would be no need to copy the fields. > Then the events could contain parameters like: > customer.id : datatype::int > customer.name : datatype::String > These would correspond to the properties of the customer object in the > session object. Similar to the generated Dummy classes for tables, it would > be possible to create dummy classes here too. > Struts supports populating the nested properties, however, the nested class > must not be null when this occurs, otherwise an exception is thrown. This > could be achieved by requiring a default constructor for the nested class (it > should be a JavaBean anyway) and then initializing the nested fields like: > TestBean nested = new TestBean() > or writing special property getter with lazy initialization: > TestBean getNested() { > if (nested == null) nested = new TestBean(); > return nested; > } > This behaviour could be recursive, meaning customer.address.street would mean > that there is a further JavaBean as the address property of the customer > object, which has a street property.
