问题 I have got a string which consists of textlines. I would like to input these lines into a textarea with some css styles(eg changing the colour of some lines). How can this be done? 回答1: TinyMCE does do a pretty decent job of rendering CSS and other markup in an editor. To include this easily with Wicket, I suggest the org.wicketstuff.tinymce-parent package. The development/source code is in GitHub and the actual releases are in the public maven repository. You can then use a standard Wicket

问题 I successfully made an AjaxFallbackDefaultDataTable, but I want to make the contents of the cells links. How do I do this with Apache Wicket? 回答1: You can use an AbstractColumn instead of a PropertyColumn . This will allow you to add whatever component you like, rather than just the string value of the PropertyModel. columns.add(new AbstractColumn("displayModel", "sortModel") { void populateItem(Item cellItem, String componentId, IModel rowModel) { cellItem.add(new LinkPanel(componentId,

问题 I'm using "FeedbackLabels" to show component-specific validation messages, based on ideas and code in this blog post: User friendly form validation with Wicket. Problem is, pages using such FeedbackLabels for validation messages flood the log with superfluous warnings: 2012-05-04 10:43:32,824 ["http-bio-8080"-exec-6] WARN org.apache.wicket.protocol.http.WebSession - Component-targetted feedback message was left unrendered. This could be because you are missing a FeedbackPanel on the page.

问题 I just spent several hours of my life debugging this problem. I'm documenting it here for others. Question: I'm getting the following error when I try to click on an AjaxLink in Internet Explorer: Wicket: ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Object required It works fine in all other browsers; just IE is busted. 回答1: Check to make sure that your HTML is 100% syntactically correct. Ajax responses are returned to the browser inside a CDATA section, and if the payload

问题 I am trying to get the name and ip of the current server in which my web application is running on. I am not sure how to do this is wicket 1.54. I need to know how to get at my server variables. In wicket 1.4 you could do: HttpServletRequest hsr = getWebRequestCycle().getWebRequest().getHttpServletRequest(); Then you could use hsr to grab headers or attributes. Edit: In wicket 1.54 the equivalent line is: HttpServletRequest hsr = (HttpServletRequest)getRequestCycle().getRequest()

问题 I am using wicket framework, and I have made a zip file by Java code, I want to have a link to download it, I don't know if it is possible or I should make the zip file by wicket (but not Java) and then have a link to download. 回答1: Take a look at ZipResourceStream. With this class you can generate zip contents of a directory on the fly, and use a org.apache.wicket.markup.html.link.ResourceLink with ResourceStreamResource to link to it. File file = new File(path); IResourceStream resStream =
