Inmethod Grid Select All or Reload Grid
Hi there I started using the Inmethod DataGrid because I need resizable tables and I need to be able to select multi entries. First, I had the problem that I couldn't select all entries and the multi select didin't work properly. In this forum I found out that I have to implement hashCode in the model. After that it worked, but the grid didn't refresh anymore after I had changed the model. To sum up, if I use the hashCode, I the table doesn't refresh after I change the model. If I don't use hashCode, the selection doesn't work properly. The code for hashCode() and equals I'm using: public int hashCode() { return new Long(id).hashCode(); } public boolean equals(final Object obj) { if (obj == this) { return true; } else if (obj == null) { return false; } else if (obj instanceof DetachableModel) { DetachableModel other = (DetachableModel) obj; return other.id == this.id; } return false; } Thanks for your help. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Inmethod-Grid-Select-All-or-Reload-Grid-tp3456685p3456685.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Refreshing loadable detachable model object inside an ajax call
Hi Clint, Here is the example of EntityModel as taken from http://wicketinaction.com/2008/09/building-a-smart-entitymodel/ http://wicketinaction.com/2008/09/building-a-smart-entitymodel/ . I've added the constructor that calls super(). public class EntityModelT extends AbstractEntityModelT { public EntityModel(Class? extends T clazz, Serializable id) { super(clazz, id); } @Override protected T load(Class clazz, Serializable id) { return WicketApplication.get().get_service().load(clazz, id); } } Now my I have two errors from my IDE (Eclipse), the first one on extends AbstractEntityModelT {. On type T, it says: Bound mismatch: The type T is not a valid substitute for the bounded parameter T extends Identifiable? of the type AbstractEntityModelT. Would you know what is going on here? I am following the exact example. The second error my IDE is complaining about is on return WicketApplication.get().get_service().load(clazz, id);: The method load(ClassT, long) in the type Service is not applicable for the arguments (Class, Serializable). That's fair enough since all the objects ID i'm persisting to DB are of type Long. But why is the example using type Serializable instead of Long? If you look at the section Using EntityModel to bind to Forms, from the link above you will see that the values passed are class and Long: public EditPersonPage(Long personId) { this(new EntityModelPerson(Person.class, personId)); } I fear I'm missing a very small detail that's stopping me from having this working.

Re: Refreshing loadable detachable model object inside an ajax call
Your issue with the generics is you need to tell it that 'T extends Indetifiable', or take it out entirely if you are going to explicitly tell it that you are using the Parent class. Also feel free to make the argument match what your load method requires. The article could be referencing code that is old or whatever. Also keep in mind that the class Long implements Serializable, but the primitive long (lower case 'l') isn't an object and doesn't have a type inheritance (even though it will serialize, but that's a disfferent topic). -Clint public class EntityModelT *extends Identifiable* extends AbstractEntityModelT { public EntityModel(Class? extends T clazz, Serializable id) { super(clazz, id); } @Override protected T load(Class clazz, Serializable id) { return WicketApplication.get().get_ service().load(clazz, id); } } On Mon, Apr 18, 2011 at 6:16 AM, lucast lucastol...@hotmail.com wrote: Hi jcgarciam, I have made sure that my original class Parent does implement class IdentifiableSerializable and I have now modified EntityModelT to public class EntityModelT extends AbstractEntityModelParent {.

Re: Inmethod Grid Select All or Reload Grid
For what you're saying, I believe you've got something messed up in your Bean's hashCode and equals method. Inmethod's Datagrid keeps a Set (HashSet) of IModel objects to keep track of which items are selected. If you've implemented correctly the equals method in your bean and believe that there's something wrong in the way the Datagrid keeps track of selected items, you can implement your own isItemSelected, resetSelectedItems, selectAllVisibleItems methods in a custom implementation of Datagrid or Abstractdatagrid. -- Marc Nuri On Mon, Apr 18, 2011 at 14:19, GJT taulant.gju...@helvetic.com wrote: After debugging, I found out the with the hashCode method, the columns don't load.

extends statement
Hello, I created a web application with module as reausable component in it. Here is how it looks like (very simple): Index.html - 2 links (they are in ul list) and module added through div Index.Java extends HomePage with three add statements (2 x BookmarkablePageLink and one ModuleOne()) OtherPage.html - 2 links (they are in ul list) and module added through div OtherPage.java - extends HomePage with three add statements (2 x BookmarkablePageLink and one ModuleTwo()) When I run the application both modules show up and links don't work.. Can both pages extend HomePage? Thank you for your comments.
Wicket and youtube browser based upload
Hi There! I'm quite new to wicket and I'm doing a web application where user's can upload videos to youtube. For that, there is an youtube API from google. The problem I have is that I need to use browser-based upload, which means, that the actual upload should go directly to youtube and not to the server, where my application is running. And that is the point where my lack knowledge of wicket is stopping me. Basically I would like to present a user a form, where he can enter some values about the video (name, category, etc), the file he wants to upload. This form should be submitted than to the youtube site with post method and some extra parameters. But I actually don't know how to do that. Can I change target in standard wicket form? And if I use the form in popup, how will I close the popup if the form goes to youtube? Has anyone experience with this? I don't know what else information to write here, so if anything more is needed ask for it. I hope someone will help me. Thanx, Pavol

The error is in the model you gave your form. Since you aren't explicitly stating a model for the DDC, it is assuming a CompoundPropertyModel on the parent form. I suspect your form declaration is something like new Form(form,new CompoundPropertyModel(getUserName())) It should be something like new Form(form,new CompoundPropertyModel(new User())) I'm personally not a fan of CPMs and prefer explicitly setting the model for each of my components. -Clint On Mon, Apr 18, 2011 at 11:59 PM, cablepuff cablep...@gmail.com wrote: Hi I have the following domain object public class User { private String email; private String firstName; private String lastName; private Account account; public String getUserName() { return this.account.getName(); } public void setUserName(String username) { this.account.setName(username); } } I have a form with dropdownchoice. final DropDownChoiceUser userChoice = new DropDownChoicePerson(userChoice, new ListModelUser(users), new ChoiceRendererUser(userName, userName)); When the page loads i get this error! org.apache.wicket.WicketRuntimeException: No get method defined for class: class java.lang.String expression: userName at org.apache.wicket.util.lang.PropertyResolver.getGetAndSetter(PropertyResolver.java:492) at org.apache.wicket.util.lang.PropertyResolver.getObjectAndGetSetter(PropertyResolver.java:332) at org.apache.wicket.util.lang.PropertyResolver.getObjectAndGetSetter(PropertyResolver.java:242) at org.apache.wicket.util.lang.PropertyResolver.getValue(PropertyResolver.java:95) at org.apache.wicket.markup.html.form.ChoiceRenderer.getIdValue(ChoiceRenderer.java:145) at org.apache.wicket.markup.html.form.AbstractSingleSelectChoice.getModelValue(AbstractSingleSelectChoice.java:166) at org.apache.wicket.markup.html.form.FormComponent.getValue(FormComponent.java:879) at org.apache.wicket.markup.html.form.AbstractChoice.onComponentTagBody(AbstractChoice.java:353) at org.apache.wicket.Component.renderComponent(Component.java:2690) at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1539) at org.apache.wicket.Component.render(Component.java:2521) at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1441) at org.apache.wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:1604) at org.apache.wicket.MarkupContainer.onComponentTagBody(MarkupContainer.java:1528) at org.apache.wicket.markup.html.form.Form.onComponentTagBody(Form.java:2012) at org.apache.wicket.Component.renderComponent(Component.java:2690) at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1539) at org.apache.wicket.Component.render(Component.java:2521) at org.apache.wicket.markup.html.border.Border$BorderBodyContainer.resolve(Border.java:421) at org.apache.wicket.markup.resolver.ComponentResolvers.resolve(ComponentResolvers.java:65) at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1445) at org.apache.wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:1604) at org.apache.wicket.MarkupContainer.onComponentTagBody(MarkupContainer.java:1528) at org.apache.wicket.markup.html.border.Border$BorderBodyContainer.onComponentTagBody(Border.java:403) at org.apache.wicket.Component.renderComponent(Component.java:2690) at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1539) at org.apache.wicket.Component.render(Component.java:2521) at org.apache.wicket.markup.html.border.Border.resolve(Border.java:287) at org.apache.wicket.markup.resolver.ComponentResolvers.resolve(ComponentResolvers.java:65) at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1445) at org.apache.wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:1604) at org.apache.wicket.MarkupContainer.onComponentTagBody(MarkupContainer.java:1528) at org.apache.wicket.markup.html.border.Border$BorderBodyContainer.onComponentTagBody(Border.java:403) at org.apache.wicket.Component.renderComponent(Component.java:2690) at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1539) at org.apache.wicket.Component.render(Component.java:2521) at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1441) at org.apache.wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:1604) at org.apache.wicket.MarkupContainer.renderAssociatedMarkup(MarkupContainer.java:697) at org.apache.wicket.markup.html.border.Border.onComponentTagBody(Border.java:328) at org.apache.wicket.Component.renderComponent(Component.java:2690) at
