I noticed that if I have an inputText control and a commandButton, hitting enter on the textfield just does a postback, whereas, on a non JSF driven page, hitting enter just submits the default button on the page.

Does this mean that I must also supply a listener on the inputText control that calls the same method in my bean as the commandButton?

Gregg,

I'm not quite sure what you mean -- hitting enter on a JSF form usually defaults to the first button, like any other HTML form. Let's say you had a navigation rule like this:

And you have a page like this:

If you hit enter, it'll execute the "default" button, and try to load "anotherpage.jsp". If you click on the "not default" button, it'll simply redisplay the page.

Well, I have something strange happening. I have a login page and after I type my username and password I hit and enter and everything works fine. I have another page with a single textfield and a button for looking up an employee by their ID number. I type in the ID and hit enter and the page just posts back to itself. If I click the Button, it works as expected, navigating to another page. There is nothing else on the page except a label.

Hmmm.. What version of IE do you have? And can you show us the page you're having a problem with?

I have IE 6.0. Here is the employeelookup.jsp:

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<f:view>

</head>
<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">

<h:form id="search">

    <h:panelGrid columns="2" cellpadding="0" cellspacing="0" border="0">
        <h:graphicImage url="images/search.gif"/>
        <h:panelGrid columns="3" cellpadding="3" cellspacing="0" border="0" headerClass="login-heading">
            <f:facet name="header">
                <h:outputFormat value="Employee Lookup"/>
            </f:facet>
            <h:outputLabel for="empIdInput" styleClass="commonLabel">
                <h:outputText value="Enter an Employee ID number:"/>
            </h:outputLabel>
            <h:inputText id="empIdInput" required="true" value="#{employeeLookupBean.empId}" styleClass="textbox" >
                <f:validateLength minimum="4" maximum="5"/>
            </h:inputText>
            <h:message for="empIdInput" styleClass="error" />
            <h:panelGroup />
                <h:commandButton action="#{employeeLookupBean.lookup}" title="submit" value="Lookup" styleClass="buttonStyle"/>
            <h:panelGroup />
            </h:panelGrid>
        </h:panelGrid>
    <f:verbatim>
        </div>
    </f:verbatim>
</h:form>
<jsp:include page="footer.jsp" />
</body>
</html>
</f:view>

And here is the EmployeeLookupBean.java

import com.gthought.anykey.stores.Employee;
import com.gthought.anykey.stores.Call;
import com.gthought.anykey.utils.Constants;
 
import javax.faces.context.FacesContext;
 
public class EmployeeLookupBean extends BaseBean
{
    private Integer empId;
 
    public Integer getEmpId()
    {
        return empId;
    }
 
    public void setEmpId(Integer empId)
    {
        this.empId = empId;
    }
 
    public String lookup()
    {
        FacesContext context = getFacesContext();
        Employee newEmployee = new Employee();
        Call newCall = new Call();
        newEmployee.setDepartment("PC Support");
        newEmployee.setEmpId(empId);
        newEmployee.setFirstName("Gregg");
        newEmployee.setLastName("Bolinger");
        newEmployee.setPhone("1775");
        newEmployee.setMailStop("3.3");
        newEmployee.setEmail("Gregg.Bolinger@intrustbank.com");
        newCall.setEmployee(newEmployee);
        getApplication().createValueBinding("#{" + Constants.CALL_KEY_SCOPE + "." + Constants.CALL_KEY + "}").setValue(context, newCall);
        return "success";
    }
}

Here is the Navigation Rule:

The only difference between the way I constructed this page and the way I constructed the login page is that this page has a header which has some commandLinks in them. Could it be that one of the commandLinks is taking the default away from my Lookup commandButton? But then again, why would it work in Firefox and not IE if this was the case?
