问题 Let's say I have an object hierarchy like this: Account > Site > Supply An Account is an actual company, a Site is a building they have, and a Supply is either an ElecSupply or GasSupply . Supply is never instantiated and could be an abstract class in theory. I am using Objectify for persistence, and have a page that displays the list of Supplies for each Site, regardless of whether they are an ElecSupply or GasSupply . Now I am implementing the GWT Editor Framework and have come up against a

问题 I have searched around and been trying to figure out if I can use the editor framework with polymorphic types. I found this post at Using GWT Editors with a complex usecase which is close to what I am trying to do. I am fairly new to the editor framework, so any help would be much appreciated. For example, here is some of the code, Data Transfer Objects: public class Employee{ public List<Contact> contacts } public class Contact { public class ContactEmail extends Contact {} public class

问题 I am using GWT 2.5.0 My intent was to create an editor hierarchy which binds to a ParentBean object. The ParentBean contains a List<Group> , and the Group bean has a List<ChildBean> and List<Group> . From the Editor tutorials I have found, it seemed simple enough to create an editor which contains a ListEditor as one of its sub-editors. But the parent editor never seems to properly initialize the sub ListEditor. Here is an explanation of how I attempted to do this. From the code below, I

问题 I'm using gwt-platform and tried to implement GWT's editor framework. But I don't get it working from within the presenter. There are some answers around the web, that say I have to inject the EditorDriver somehow into the Presenter, but I don't know how to do this... At the moment I tried this without success: public class MyPresenter extends Presenter<MyPresenter.MyView, MyPresenter.MyProxy> implements MyUiHandlers { public interface MyView extends View, HasUiHandlers<MyUiHandlers>, Editor

问题 I'm trying to create a page which is very similar to the Google Form creation page. This is how I am attempting to model it using the GWT MVP framework (Places and Activities), and Editors. CreateFormActivity (Activity and presenter) CreateFormView (interface for view, with nested Presenter interface) CreateFormViewImpl (implements CreateFormView and Editor< FormProxy > CreateFormViewImpl has the following sub-editors: TextBox title TextBox description QuestionListEditor questionList

问题 I've got a value type Commission that's part of a larger editor graph: public class Commission implements Serializable { private CommissionType commissionType; // enum private Money value; // custom type, backed by BigDecimal private Integer multiplier; private Integer contractMonths; // ... } What I want to achieve is to initially only show the dropdown for the commissionType enum, and then select an appropriate sub-editor to edit the rest of the fields based on the value selected: I have

问题 I have a working NullableStringListEditor implementation: public class NullableStringListEditor extends Composite implements IsEditor<OptionalFieldEditor< List<String>, ListEditor<String, StringEditor> >> {...} Now, I am building a NullableStringSetEditor by wrapping it: public class NullableStringSetEditor extends Composite implements ValueAwareEditor<Set<String>>, LeafValueEditor<Set<String>> { private NullableStringListEditor wrappedEditor = new NullableStringListEditor(); @Override public

问题 See the orignal question for context. Additional Context: Objectify-Appengine is used for persistence. FormProxy and QuestionProxy are of type EntityProxy QuestionDataProxy and its subtypes are of type ValueProxy All Editors implement HasRequestContext , and in the case of QuestionData subtype Editors, HasRequestContext.setContext() is called explicitly from the parent. The first problem has to do with Collections, and the second has to do with Polymorphic types. I'm not sure if the problem

问题 I have a HashMap inside my POJO that I am using the Editor framework in GWT to edit. While I have access to the standard member variables bound through thier getters/setters, I don't know how to access the values inside the HashMap. How do I get access to the underlying POJO that is being edited through my editor that is using the SimpleBeanEditorDriver? My POJO: @Entity(noClassnameStored=true) public class ProfileConfig extends BaseEntity { @Indexed(unique=true) private String name; private
