    <p>I am experiencing some issues with the application. I have a registration form which is post to another page from the controller this page displays the results of the query from the registration form. On the results page i select a record and it returns me with the data to the registration page. The user should be able to update the record once its returned or execute a query again.</p> <p>The problems i am having is when the user is on the registration form and executes a query they are posted to the results page the results page is displayed however the url does not change. The registration url is <code>http://localhost:8084/crimeTrack/citizen_registration.htm</code> when posted to the results page by clicking the query button the url is still <code>http://localhost:8084/crimeTrack/citizen_registration.htm</code> when a record is clicked/selected on the results page (which has several records) the user is posted back to the registration page with the selected record and it is displayed for the user to now execute an update or a query again, the url is <code>http://localhost:8084/crimeTrack/getCitizen/1985121244.htm</code> and the user is now on the registration page.</p> <p>If i click query/update again i am getting an <strong>HTTP 400 error</strong> and the url is reading <code>http://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm/</code> and this is not a valid URL mapping in the Controller. I think the url should be <code>http://localhost:8084/crimeTrack/citizen_registration.htm</code> when the registration page is requested. I am not sure when the POST from the results page takes the user back to the registration page is the url should be <code>http://localhost:8084/crimeTrack/getCitizen/1985121244.htm</code> the attached number is the citizen number. Under is my code i am not sure if i am doing these calls correctly and i would like an explanation for the results i am getting as well as a solution to the issues experienced;</p> <p>Pages are submitted using <strong>jquery</strong>:</p> <p>This is an example for the registration page and all other pages follow the same pattern</p> <p><strong>JScript</strong> </p> <pre><code>function submitPage(){ document.getElementById("citizenRegistration").action="citizen_registration.htm"; //document.getElementById("citizenRegistration").target="_self"; document.getElementById("citizenRegistration").method = "POST"; document.getElementById("citizenRegistration").submit(); } </code></pre> <p><strong>citizen_registration.jsp</strong></p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0//EN"&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;title&gt;Citizen Registration&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="tab1" class="divGroup"&gt; &lt;form:form id="citizenRegistration" name ="citizenRegistration" commandName="citizens"&gt; ........................ &lt;div class="buttons"&gt; &lt;ol&gt; &lt;li&gt;&lt;input class="button" id="save" type="submit" name= "user_request" value="Save"/&gt; &lt;input class="button" id="update" type="submit" name= "user_request" value="Update"/&gt; &lt;input class="button" id="query" type="submit" name= "user_request" value="Query"/&gt; &lt;/li&gt; &lt;/form:form&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><strong>citizenList.jsp</strong></p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;script type="text/javascript"&gt; function submitPage(socialSecurityNumber){ document.getElementById("citizenList").action="getCitizen/1985121244.htm";//harded coded for testing //document.getElementById("citizenList").target="_self"; document.getElementById("citizenList").method = "POST"; document.getElementById("citizenList").submit(); } function GetCitizenTypeDescription(citizenTypeId){ $.ajax({ type:'GET', url:'getCitizenTypeDescription.htm', data:{citizenTypeId:citizenTypeId}, dataType: 'text', success: function (data) { $('.citizenTypeId').each(function(i){ if($(this).val() === citizenTypeId){ //finds parent div var parent = $(this).parent(); //search for child element wit class name citizenTypeDesc var thisCitizenTypeDesc = parent.children('.citizenTypeDesc'); thisCitizenTypeDesc.text(data); } }); } }); } &lt;title&gt;Citizen Search Results&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form:form id="citizenList" name ="citizenList"&gt; &lt;div id ="content"&gt; &lt;c:forEach items="${citizens}" var="citizen"&gt; &lt;div id="table"&gt; &lt;div&gt; &lt;p&gt;&lt;canvas class="canvas" height="240" width="320"&gt;&lt;/canvas&gt; &lt;/div&gt; &lt;label class="citizenTypeDesc"&gt;&lt;/label&gt;&lt;/br&gt; &lt;a class="socialSecurityNumber" href="${citizen.socialSecurityNumber}"&gt;${citizen.fName} ${citizen.lName}&lt;/a&gt; &lt;input type="hidden" id="photo" value="${citizen.photo}" class="photos"/&gt; &lt;input type="hidden" id="socialSecurityNumber" value="${citizen.socialSecurityNumber}" /&gt; &lt;input type="hidden" class="citizenTypeId" value="${citizen.citizenTypeId}"/&gt; &lt;/div&gt; &lt;/c:forEach&gt; &lt;/div&gt; &lt;/form:form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><strong>CitizenRegistrationController.java</strong></p> <pre><code>@Controller public class CitizenRegistrationController { private final Logger logger = Logger.getLogger(getClass()); @Autowired private CitizenTypeManager citizenTypeManager; ............

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
