    <p>I want to build a small UI which will offer the user the posibility to write some math formulas in an easier way(hence the UI) and be able to save them to a .txt (or something similar) file. </p> <p>For example: I have 3 selectboxes which offer a variety of options, some buttons which represent math operations and an inputTextArea. So far I've managed to link selected content from each selectOneMenu and from a few inputText's and concatenate them with what i need and write the created math formulas to a .txt file.</p> <p>Now I want to offer the user the possibility to see the formula he is writing(by selecting content and pressing buttons) as he is doing it. So far I've been trying to do that using an inputTextArea but the best I managed was to transfer the selected content from <strong>only one</strong> selectOneMenu to the textArea and after that all my attempts to add every action the user makes to the text area have failed(someone suggested using <code>&lt;h:panelGroup&gt;</code> but I got nowhere with that, I tried to combine all the beans I used to fill the menus into one bean and somehow go from there , but that didn't work either).</p> <p>A sample of the JSF part I've been working on so far, with 2 selectboxes and the TextArea:</p> <pre class="lang-html prettyprint-override"><code>&lt;h:outputText value="Formula Name"&gt;&lt;/h:outputText&gt; &lt;h:inputText value="#{output.formulaName}" id="formulaName"&gt;&lt;/h:inputText&gt; &lt;br /&gt;&lt;br /&gt; The formula so far: &lt;h:inputTextarea value="#{output.propertyReferenceValue}"&gt;&lt;/h:inputTextarea&gt; &lt;br/&gt;&lt;br/&gt;&lt;br/&gt; Property1: &lt;h:selectOneMenu value ="#{output.propertyReferenceValue}" id="selectTwo" valueChangeListener="#{output.propertyReferenceValueChanged}" onchange="submit()"&gt; &lt;f:selectItems value="#{property.propertyReference}"/&gt; &lt;/h:selectOneMenu&gt; &lt;br/&gt;&lt;br/&gt; Property2: &lt;h:selectOneMenu value ="#{output.property2ReferenceValue}" id="selectThree" valueChangeListener="#{output.property2ReferenceChangedValue}" onchange="submit()"&gt; &lt;f:selectItems value="#{property2.property2Refference}" /&gt; &lt;/h:selectOneMenu&gt; </code></pre> <p>Any help would be appreciated. </p> <p>PS. I'm very new to JSF(started about 2 days ago) so I will appreciate even being pointed to some documentation which might cover this or similar problems.</p>

    1. COThose `valueChangeListener`s are basically hacks. You seem not to be interested in a value change, but only in the submitted value. Before posting an answer, I'd like to know if you're using JSF 1.x or 2.x. Posting the both listener methods would also be helpful to understand what exactly you're trying to achieve with the input and output.

    2. COI am using JSF 2.0. I don't have the last version of the app on this computer(posting from laptop now) but the listener methods looked something like this: public void propertyReferenceValueChanged(ValueChangeEvent e){ propertyReferenceValue=e.getNewValue().toString(); } The other listener was similar. Hope i managed to clear things up a bit.

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.
