    <p>I need to make a small form where user types a number into the inputField, and clicks on a button, then is sent to a page, using that number as a parameter to the page.</p> <p>So far I got into this:</p> <pre><code>&lt;p:inputText id="myText" style="width:75px;" /&gt; &lt;p:commandButton id="myButton" value="Ir" action="/site/page.xhtml?id=${param['form:myButton']}" title="Ir" ajax="false" proces="@this,myText" /&gt; </code></pre> <p>tried with <code>${param['form:myButton']}</code> and <code>#{param['form:myButton']}</code>, error is the same.</p> <p>Problem is, JSF thinks its a method expression...</p> <pre><code>GRAVE: Servlet.service() for servlet [Faces Servlet] in context with path [/intranet] threw exception [/myPage action="/site/page.xhtml?id=${param['form:myButton']}".xhtml @95,41 action="/site/page.xhtml?id=${param['form:myButton']}" Not a Valid Method Expression: action="/site/page.xhtml?id=${param['form:myButton']}" with root cause javax.el.ELException: Not a Valid Method Expression: action="/site/page.xhtml?id=${param['form:myButton']}" at org.apache.el.lang.ExpressionBuilder.createMethodExpression(ExpressionBuilder.java:236) at org.apache.el.ExpressionFactoryImpl.createMethodExpression(ExpressionFactoryImpl.java:55) at org.jboss.weld.util.el.ForwardingExpressionFactory.createMethodExpression(ForwardingExpressionFactory.java:43) at org.jboss.weld.el.WeldExpressionFactory.createMethodExpression(WeldExpressionFactory.java:64) at com.sun.faces.facelets.tag.TagAttributeImpl.getMethodExpression(TagAttributeImpl.java:222) at com.sun.faces.facelets.tag.jsf.ActionSourceRule$ActionMapper2.applyMetadata(ActionSourceRule.java:104) at com.sun.faces.facelets.tag.MetadataImpl.applyMetadata(MetadataImpl.java:81) at javax.faces.view.facelets.MetaTagHandler.setAttributes(MetaTagHandler.java:129) at javax.faces.view.facelets.DelegatingMetaTagHandler.setAttributes(DelegatingMetaTagHandler.java:102) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.doNewComponentActions(ComponentTagHandlerDelegateImpl.java:402) </code></pre> <p>and this is the bottom-most exception trace.</p> <p>Question: how can I pass the value typed into of the input-field into the action of the Button when the button is clicked, so the browser navigates to the desired page passing the value in the input as a parameter, without resorting to a backing bean.</p> <p>I don't need to communicate with the server, just forward the page.</p> <p>any solution using jQuery or plain javascript in tandem with JSF is acceptable too.</p> <p>using mojarra, primefaces 3.3.1</p>

    1. COYou are doing it wrong. action expects a java Method as an EL. for eg: #{bean.someMethod}. Where 'bean' is a JSF ManagedBean. To pass value use #{bean.someMethod(someValue)}. See more here: http://balusc.blogspot.in/2011/09/communication-in-jsf-20.html

    2. CO`<p:commandButton>`'s action can have a string instead of a Java Method. it sends you to a page when you click the button. I do not want a method expression.

    3. COThe concrete functional requirement is unclear. Do you want do perform a GET form submit or do you want to perform a POST form submit and then a redirect to the desired GET URL?

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.

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