    copied!<p>I'm sorry for posting so many questions, I think I need to read up more...</p> <p>But first of all I was wondering if you guys can help me on this cos it's been bugging me for quite some time already and have been wondering why it's not working.</p> <p>(This has nothing to do with the previous errors. Haven't got to solve that, and a new one is out :x)</p> <p>I have a list that I want to populate to another, but in the process of doing so I got the error as titled :<code>The requested list key could not be resolved as a collection/array/map/enumeration/iterator type.</code></p> <p>I've looked around and tried the code but still it doesn't really seem to work. Here's my code:</p> <p>JSP (and jquery):</p> <pre><code>&lt;s:select id="feb" name="feb" headerKey="-1" list="febList" listKey="key" listValue="description" theme="simple" cssClass="formfields" /&gt; $('select#feb').change(function() { $.ajax({ url: "AnnotateSearchList?feb="+$(this).val()+"&amp;dept="+$("#dept").val(), dataType :'json', type:'GET', contentType: 'application/json', success : function(data) { alert('test'); }, error: function(){ alert('Error'); } }) }); </code></pre> <p>The method: public String doGetSelectedList() {</p> <pre><code> this.output = new StringBufferInputStream(""); SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy"); Calendar startCalendar = Calendar.getInstance(); startCalendar.add(Calendar.DAY_OF_YEAR, -3); Calendar endCalendar = Calendar.getInstance(); if (this.startDate == null || this.startDate.equals("")) { this.startDate = sdf.format(startCalendar.getTime()).toString(); } if (this.endDate == null || this.endDate.equals("")) { this.endDate = sdf.format(endCalendar.getTime()).toString(); } System.out.println("Feb "+this.feb); System.out.println("Dept "+this.dept); this.optionList =xxx.getList(this.feb, this.dept, this.startDate, this.endDate); ArrayList&lt;SelectItemsData&gt; optList = new ArrayList&lt;SelectItemsData&gt;(); for(String list : optionList){ optList.add(new SelectItemsData(list, list)); } System.out.println("Size of list: "+this.optionList.size()); System.out.println(optList.size()); String json = new Gson().toJson(optList); logger.sendMessage(getClass().getSimpleName(), LogHandler.INFO, json); //System.out.println(json); try { response.setContentType("Application/json"); response.getWriter().write(json); this.output = new StringBufferInputStream(json); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return SUCCESS; } </code></pre> <p>//The Data holder for SelectItemsData: SelectItemsData(String key, String description);</p> <p>struts/xml:</p> <pre><code> &lt;action name="AnnotateSearchList" class="mycompanyName.ajax.actions.ParetoChartCore" method="doGetSelectedList"&gt; &lt;result type="stream"&gt; &lt;param name="contentType"&gt;application/json&lt;/param&gt; &lt;param name="inputName"&gt;output&lt;/param&gt; &lt;/result&gt; &lt;result name="success"&gt;/ParetoChart.jsp&lt;/result&gt; &lt;/action&gt; </code></pre> <p>Am I going on wrong anywhere? My results are actually returning to the same page, so I thought that might be the possible cause of the error. Thanks.</p>
