    <p>I have a page where a SelectOneMenu is rendered whether there is some info on DB or not. My form looks like this:</p> <pre><code>... &lt;h:form id="wrapperUpload" enctype="multipart/form-data" &gt; &lt;h:outputLabel for="option" value="Tipo de carga: " rendered="#{uploadFile.check(userVerifier.dependencia)}" /&gt; &lt;h:selectOneMenu id="option" value="#{uploadFile.optionSelected}" rendered="#{uploadFile.check(userVerifier.dependencia)}" &gt; &lt;f:selectItems value="#{uploadFile.options}" /&gt; &lt;/h:selectOneMenu&gt; &lt;h:outputLabel for="upfile" value="Archivo: " /&gt; &lt;t:inputFileUpload id="upfile" required="true" value="#{uploadFile.upFile}" /&gt; &lt;h:commandButton value="Validar #{userVerifier.dependencia}" action="#{uploadFile.upload}" onclick="return confirmation()" &gt; &lt;f:param name="dependencia" value="#{userVerifier.dependencia}" /&gt; &lt;/h:commandButton&gt; &lt;/h:form&gt; ... </code></pre> <p>And my Beans is</p> <pre><code>private UploadedFile upFile; private boolean showOptions = false; private final String[] options = { "Seleccione una opción.", "Cargar toda la información.", "Cargar solo información errónea." }; private String optionSelected; private Database db = new Database(); public UploadedFile getUpFile() { return upFile; } public void setUpFile(UploadedFile upFile) { this.upFile = upFile; } public String[] getOptions() { return options; } public void setOptionSelected(String optionSelected) { this.optionSelected = optionSelected; } public String getOptionSelected() { return optionSelected; } public boolean check(String dependencia) { String hasInfo; hasInfo = db.checkForInfo(dependencia); if (hasInfo.equals("T")) { showOptions = true; } else { showOptions = false; } return showOptions; } public String upload() { byte[] buffer = null; int count = 0; File serverFile = null; InputStream input = null; OutputStream output = null; Map&lt;String, String&gt; params = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap(); String dependencia = params.get("dependencia"); String extension = FilenameUtils.getExtension(upFile.getName()); System.out.println("__depend: " + dependencia); System.out.println("__option: " + optionSelected); //null ... ... </code></pre> <p>Finally when I hit the button the value of SelectOneMenu (or selectedOption in my bean) is always null... How to fix this? Am I missing something?</p> <p>Forgot to mention that, if I delete the render part everything works fine...</p>

    1. COThis is not real code. You don't have an `isCheck()` method, nor are you using `rendered="#{uploadFile.check('somestring')}"`. It would already throw an EL exception while displaying the form. Please show the real code.

    3. COThe `rendered="#{uploadFile.check}"` expects a `public boolean isCheck()` method, not a `public boolean check(String dependencies)` method. It should have thrown an EL exception. What container are you using?

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.
