How to use enum values in f:selectItem(s)
(4 answers)
Closed 3 years ago.
I'm facing some problems with this widget:
<h:panelGroup>
<p:selectOneRadio required="true"
requiredMessage="Seleziona un elemento"
value="#{createCustomerView.customer.humanSex}">
<f:selectItems value="#{createCustomerView.values}"
var="humanSex" itemValue="humanSex"
itemLabel="#{humanSex.label}" />
</p:selectOneRadio>
</h:panelGroup>
The problem is that the value is not set into my instance of customer. Where am I wrong? This is the enum used in the selection for the user
public enum HumanSex {
MAN(1, "Maschio"), WOMAN(2, "Femmina");
public int id;
public String label;
private HumanSex(int id, String label) {
this.id = id;
this.label = label;
}
private HumanSex() {
}
//SET and GETTERS
}

I'm using netbeans with glassfish
In my .xhtml file, a have a link which I expect to call action shopBean.instructorScheduleById()
<p:commandLink styleClass="tooltip tour-sched"
rendered="#{shopBean.instructorSchedule!=null}"
update=":dialogFormTS" action="#
{shopBean.instructorScheduleById()}"
oncomplete="dlgTS.show()" process="#this"
ajax="true">TS<h:outputText styleClass="tooltiptext"
value="#{shopBean.instructorSchedule.name}"/>
</p:commandLink>
Bean file
#ManagedBean(name = "shopBean")
#SessionScoped
public class ShopBean {
public ShopBean() {}
public void getInstructorScheduleById(){
System.out.println("hello");
}
}
I looked to my Developer tools under network i see there is an ajax request but when i looked on glassfish output, there's no word hello
Base on what i have learned here at stackoverflow, the get prefix is used for getter methods which means it must have a return value.
public void sum(){
int num1 = 1;
int num2 = 2;
System.out.println(num1 + num2);
}
// xhtml
<p:commandButton action="#{bean.sum()}" />
if you want get the value from a getter method:
pivate int sum;
public int getSum(){
return this.sum;
}
public void setSum(sum){
this.sum = sum;
}
// xhtml
<p:outputText value="#{bean.sum}" />
The quick solution for your problem is to remove the get prefix in your
bean.

How to write a hardcoded string value inside EL expression #{ } in JSF?
(1 answer)
Closed 6 years ago.
I tried to parse argument with JSF to managed bean with ajax. my JSF code is this
<h:commandLink id="user" action="#{pageBean.setPage("user")}" >
user
<f:ajax execute="user" render="contentBody" />
</h:commandLink>
managed bean is this
#ManagedBean
public class PageBean {
private String path;
private String page;
public PageBean() {
}
#PostConstruct
public void init(){
path = "/WEB-INF/dashboard.xhtml";
}
public String getPath() {
return path;
}
public void setPath(String path) {
this.path = path;
}
public String getPage() {
return page;
}
public void setPage(String page) {
this.page = page;
}
}
But when I run this I got following error. Why is that?
Error Parsing /WEB-INF/templete.xhtml: Error Traced[line: 37] Element type "h:commandLink" must be followed by either attribute specifications, ">" or "/>".
You are using double quotes in your attribute around user.
<h:commandLink id="user" action="#{pageBean.setPage("user")}" >
This results in templete.xml not beeing a valid XML-File.
Correct example line using single quotes (as proposed by #gWombat):
<h:commandLink id="user" action="#{pageBean.setPage('user')}" >
You should use simple quotes around the parameter user:
action="#{pageBean.setPage('user')}"

javax.el.PropertyNotFoundException: The class 'xxx' does not have a readable property 'yyy'

Closed 7 years ago.
(intro: I have generated Entity Clases from DB with one tabe lets say Beans, so it generated me Beans.java, BeansFacade.java, BeansController.java and AbstracFacade.java than I added JSF pages from entity classes, and just want to add something to list.xhtml)
In my BeansFacade.java I have
public String simple(){
return "output";
}
In BeansController.java I hava
public String printSimple(){
return ejbFacade.simple();
}
And than whem I try to print that
<h:outputText value="#{beansController.printSimple}"> </h:outputText>
I get an error
javax.el.PropertyNotFoundException:
The class 'fct.entity.EventsController' does not have the property 'printSimple'.
You are not able to call the method in h:outputText.
h:outputText tries to search the given variable related getter/setter
private String printSimple;
public String getPrintSimple()
{
return ejbFacade.simple();;
}
/**
* #return the simple
*/
public String getSimple()
{
return simple;
}
And than whem you can use the simple variable to get the value.
<h:outputText value="#{beansController.printSimple}"> </h:outputText>
before that call the printSimple method.

javax.el.PropertyNotWritableException: /index.xhtml #29,118 value="": Illegal Syntax for Set Operation
(1 answer)
Closed 5 years ago.
I have this form:
<h:form>
<h:outputLabel value="Entrez un id du compte a supprimer" for="id"/>
<h:inputText id="id" value=""/>
<h:commandButton id="supprimer" value="Supprimer" action="#{compteBancaireMBean.supprimer}"/>
</h:form>
And this action method:
public String supprimer() {
gestionnaireDeCompteBancaire.supprimer(comptebancaire.getId());
return "CompteList";
}
When I submit the form, I get the following exception:
javax.el.PropertyNotWritableException: /Supprimer.xhtml #14,44 value="": Illegal Syntax for Set Operation
How is this caused and how can I solve it?
value="" does not mean anything to the JSF el parser, it can't make sense of that. You need to actually provide a static value there, as in value="Some Text" or bind it to a variable in your backing bean as in value="#{compteBancaireMBean.myVariable}" where myVariable corresponds to an actual variable in your compteBancaireMBean backing bean. This variable must follow the javabean conventions i.e. you must have
private Integer myVariable; //I use Integer here just as an example, you can use any core java type
public void setMyVariable(Integer myVariable){
this.myVariable = myVariable
}
public Integer getMyVariable(){
return this.myVariable
}
