    <p>I have a drop down in a jsp page having the following code</p> <pre><code>&lt;s:select name="newQuestion.CertificationId" list="certificationList" listKey="certificationId" listValue="certificationName" headerKey="" headerValue="Select Certification" label="Certification Name" onchange="getQuestionsList(this.value)" /&gt; </code></pre> <p>Now the on change event of the drop down is calling a JS function getQuestionsList() which intends to fetch the question list of the certification Id choosen.</p> <p>In the JS function I am submitting it to a action class where I am doing a DB call to fetch question list based on values of certification Id</p> <pre><code>function getQuestionDetails(value){ var submiturl = "Action1.action?certId="+value; $.ajax({ url:submiturl, type: 'get', beforeSend: function(){ $("#loading").show(); alert("parsed"); }, success: function(result){ if(result!=''){ } else { alert(result); } }, }); } </code></pre> <p>Now in the action class I am setting the value of questionList with values I fetch from database .questionList is a instance variable in action class with getter and setter methods.Now in struts.xml I am passing to the same jsp where I had the drop down</p> <pre><code>&lt;action name="questionAction" class="questionInfo.QuestionManager" method="displaySelectedQuestions"&gt; &lt;result name="loaded"&gt;/questionAdmin.jsp&lt;/result&gt; &lt;/action&gt; </code></pre> <p>The problem I encounter is when I go back to the jsp I am not able to retrieve the question List which I display in an iterator </p> <pre><code>&lt;table class="registrationDetailsTable"&gt; &lt;tr class="tabledataheader"&gt; &lt;td&gt;Question Id&lt;/td&gt; &lt;td&gt;Question Description&lt;/td&gt; &lt;/tr&gt; &lt;s:iterator value="questionList"&gt; &lt;tr class="tabledatarow"&gt; &lt;td&gt;&lt;s:property value="questionId" /&gt;&lt;/td&gt; &lt;td&gt;&lt;s:property value="questionDesc" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/s:iterator&gt; &lt;/table&gt; </code></pre> <p>Please let me know where I am getting wrong so that I have the question List populated in my jsp</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
