    <p>I Have a simple problem but i can't solve it.. I'm using wicket. On the web application i have a button (load). When i click that button, some data loads from the web, saves in the DataBase and then loads to the on the web application (StartPage.html). I have another button for correction that data (edit), and when i click it, EditPage.html loads. So i have just 2 pages. After some corrections on the EditPage.html I click save-button and new data updates in the DataBase and then should be loaded in the on the web application(StartPage.html).</p> <p>It's simple, but before i click the "load" button, the should be clean. So if i'll clean the table before the "load"-click it will be cleaned up every time i click the "edit"-button. i've tried to make some flags, or send parameters to the StartPage, but it seems like a circle.</p> <p>StartPage should every time loads data but 1st time cleans table but then not. The problem is to send parameters somehow..</p> <p>I hope it's clear, any suggestions?</p> <p><strong>Updated:</strong></p> <p>EditPage</p> <pre><code>public class EditPage extends WebPage { public EditPage(final PageParameters parameters) { Form&lt;?&gt; form = new Form&lt;Void&gt;("form") { @Override protected void onSubmit() { // if button "save" clicked PageParameters params = new PageParameters(); params.add("flag", "true"); setResponsePage(StartPage.class, params); } }; } } </code></pre> <p>StartPage</p> <pre><code>public class StartPage extends WebPage { public StartPage(final PageParameters parameters) { String flag = parameters.getString("flag") if (flag=="false") // Delete from DB Form&lt;?&gt; form = new Form&lt;Void&gt;("form") { @Override protected void onSubmit() { // Load from web to DB } }; // Load from DB } } </code></pre>

    1. COYou'll need to use this overload of [`RequestCycle.setResponsePage()`](http://wicket.apache.org/apidocs/1.5/org/apache/wicket/request/cycle/RequestCycle.html#setResponsePage(java.lang.Class, org.apache.wicket.request.mapper.parameter.PageParameters)). Pass it `StartPage.class` or `EditPage.class` respectively, and a `PageParameters` instance you instantiate.

    3. COyeah, but which parameter i can send from EditPage to StartPage? i've tried boolean flag but it's not make it easier.. like if i make **public Boolean flag** and then initialize it, then next time if i'll either send the parameter it will be initialized the same way and parameter won't help

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.
