    <p>I need to generate textboxes through a loop as follows.</p> <pre><code>&lt;p:panel id="dataPanel" closable="true" toggleOrientation="horizontal" toggleable="true" header="Data"&gt; &lt;h:panelGrid id="dataPanelGrid" columns="3" cellpadding="5"&gt; &lt;c:forEach var="row" items="#{zoneChargeManagedBean.list}"&gt; &lt;p:outputLabel for="txtCharge" value="#{row[1]}"/&gt; &lt;p:inputText id="txtCharge" value="#{row[2]}" converter="#{bigDecimalConverter}" onkeydown="return isNumberKey(event, this.value);" label="#{row[1]}" required="false" maxlength="45"&gt; &lt;f:validator validatorId="negativeNumberValidator"/&gt; &lt;f:attribute name="isZeroAllowed" value="false"/&gt; &lt;f:validator validatorId="bigDecimalRangeValidator"/&gt; &lt;f:attribute name="minPrecision" value="1"/&gt; &lt;f:attribute name="maxPrecision" value="33"/&gt; &lt;f:attribute name="scale" value="2"/&gt; &lt;/p:inputText&gt; &lt;p:message for="txtCharge" showSummary="false"/&gt; &lt;/c:forEach&gt; &lt;p:commandButton id="btnSubmit" update="dataPanel messages" actionListener="#{zoneChargeManagedBean.insert}" icon="ui-icon-check" value="Save"/&gt; &lt;p:commandButton value="Reset" update="dataPanel" process="@this"&gt; &lt;p:resetInput target="dataPanel" /&gt; &lt;/p:commandButton&gt; &lt;/h:panelGrid&gt; &lt;/p:panel&gt; </code></pre> <p>The value of the given textbox is a type of <code>BigDecimal</code> from the database. </p> <p>When the given command button is pressed, the values held by these textboxes should be retrieved from the corresponding JSF managed bean so that they can either be inserted or updated in the database.</p> <p>It would be even better, if it is possible to retrieve the values of all of these text fields at once in some kind of collection (like <code>java.util.List</code>), when the given button is pressed.</p>

    2. COQuestion is unclear to me. ZoneChargeManagedBean is your code and you should know best how to access its data. Using indices to access rows data seems awkward by the way but hard to tell any more without bean's code.

    3. COWhat exactly is your concrete problem? You already have a `#{zoneChargeManagedBean.list}` to hold the values. Is it empty when you check it in action method or so?

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.
