POUsing Wicket AbstractAjaxBehavior with jQuery.ajax()
text
Body
copied!<p>I have used the jQuery AJax call to send JSON as documented here in <a href="https://stackoverflow.com/questions/3168401/json-formatting-sending-json-via-jquery-ajax-post-to-java-wicket-server">StackOverflow</a></p> <p>The problem is that I am not receiving any Data on the server . I can see that the call did reach the target ajax behavior -- but in onRequest() method , the RequestCycle dd not contain any parameters</p> <p>My Wicket Code:</p> <pre><code> AbstractAjaxBehavior ajaxSaveBehaviour = new AbstractAjaxBehavior(){ private static final long serialVersionUID = 1L; @SuppressWarnings("unchecked") public void onRequest() { //get parameters final RequestCycle requestCycle = RequestCycle.get(); final PageParameters pageParameters = new PageParameters(requestCycle.getRequest().getParameterMap()); logger.info(" I have received something 1"); for(String pkey: requestCycle.getRequest().getParameterMap().keySet()){ String[] valArry= requestCycle.getRequest().getParameterMap().get(pkey); StringBuffer sb = new StringBuffer(); for(String s: valArry) sb.append(s).append(" , "); logger.info("pk :"+ pkey + " = "+ sb.toString()); } //do something using nice json library to produce a string of json logger.info(" I have received something 2"); for(String key: pageParameters.keySet()){ Object o= pageParameters.get(key); logger.info("received key : "+ key + " = " +o.toString()); } String data="ok"; requestCycle.setRequestTarget(new StringRequestTarget("application/json", "utf-8", data)); } }; add(ajaxSaveBehaviour); String callBackURL= ajaxSaveBehaviour.getCallbackUrl().toString(); </code></pre> <p>My Javascript that invokes this method</p> <pre><code>console.log(" call back url :"+ callBackURL); $.ajax({ url: callBackURL, type: 'post', cache: false, data:JSON.stringify(ccbArry[0]), contentType: 'application/json', dataType: 'json', complete: function() { alert(" completed okey dokey!") } }); </code></pre> <p>From my Firebug console, I can see that the JSON POST was made succesfully and the alert(" completed okey dokey!") dos get triggered. </p> <p>The problem is that on the Wicket AbstractAjaxBehavior is unable to find any parameters in the RequestCycle.</p> <p>Is there something I am missing ? The funny thing is that I ran this is debugger asn I could not find any parameter. This looks like an encoding issue.</p> <p>From Firebug, I could see that this was the call that was made </p> <pre><code>http://localhost:8080/mywebapp-web-1.0-SNAPSHOT/?wicket:interface=:0::IActivePageBehaviorListener:0:&wicket:ignoreIfNotActive=true&%7B%22type%22%3A9504%2C%22sourceNewsClipBean%22%3A%7B%22type%22%3A9503%2C%22id%22%3A%224cf05752acc1d6aebface86d%22%2C%22typeString%22%3A%22NEWSCLIP_TYPE%22%7D%2C%22startOffset%22%3A%22195%22%2C%22clipDuration%22%3A%22297%22%7D= </code></pre> <p>Somehow , these parameters do not apperd in the RequestCycle. It looks like an encodong issue . Any ideas ?</p>
