问题 A Wicket application serializes and caches all pages to support stateful components, as well as for supporting the back button, among other possible reasons. I have an application which uses setResponsePage to navigate from screen to screen. Over a pretty short amount of time the session gets rather large because all of the prior pages are stored in the session. For the most part, I only need the session to contain the current page, for obvious reasons, and perhaps the last 2 or 3 pages to

问题 In a custom Wicket class, not unlike the following, I'm using a service bean which should be injected by Spring, as defined with the SpringBean annotation (from the wicket-spring project). public class ReportExportFileModel extends AbstractReadOnlyModel<File> { @SpringBean(name = "reportService") ReportService reportService; ReportDto reportDto; ReportExportFileModel(ReportDto reportDto) { this.reportDto = reportDto; } @Override public File getObject() { try { return reportService

问题 I have a large library of wicket components that are annotated with a custom annotation @ReferencedResource or another annotation @ReferencedResources , that has a ReferencedResouce[] value() parameter to allow multiple annotations. Here is a sample code snippet: @ReferencedResources({ @ReferencedResource(value = Libraries.MOO_TOOLS, type = ResourceType.JAVASCRIPT), @ReferencedResource(value = "behaviors/promoteSelectOptions", type = ResourceType.JAVASCRIPT) }) public class

问题 i have been trying to trying to implement something like << < (textbox) of (totalnumberofpages) > >> any suggestions on this Thanks in advance... 回答1: If you are looking for pagination in DataView then ,all you need to do to enable paging is to call setItemsPerPage(int) on the dataview. Check following example JAVA code public class RepeatingPage extends BasePage { private static final long serialVersionUID = 1L; /** * Constructor */ public RepeatingPage() { Iterator<Contact> contacts = new

问题 Basically my java class that I want to sort should be working and we got the code for that. The thing is, when we try to simply just test if our link works(We got a link named "NAME" which should sort the list of people by the name, when clicked), by simply doing the code below. But it doesn't sort it. Our SQL is also correct so does anyone see the problem that we don't? We're fairly new to wicket. public class SimpleView extends SimpleViewPage { //denne er oprettet til brug til når der skal

问题 I have classical complaint - rebuilding and reloading the web app takes too long. I want to compile the classes (preferrably from the IDE) or change a static file and let the server check what changed and act approprietly (reload the class/file). What are my options for Wicket + JDK 1.6 ? I'd prefer Jetty, but Tomcat, JBoss AS or others are good, too. I am not using the ReloadingWicketFilter since I use mvn jetty:run-exploded because it's the simplest way to run my app with desired

问题 Hi Guys i am a beginner in java. I am currently working in apache wicket which is a java based framework. I am trying to create a load button to select and upload multiple files in a particular folder. I already have this piece of code using which i am able to select and upload a single file but i am confused doing same selecting and uploading multiple files.

问题 Im using Wicket 1.5 and I need to build a component with a FileUploadField to load an image. I need an Ajax behaviour to make a preview of image after selected it (without submiting the entire form). Searching on Google, I found this Event that match when I select the file: AjaxEventBehavior choose = new AjaxEventBehavior("onChange"){ private static final long serialVersionUID = 1L; @Override protected void onEvent(AjaxRequestTarget target) { Request request = RequestCycle.get().getRequest();
