I am getting error while running this snippet as /facelet/crew/objectMapGossip.xhtml #14,94 value="#{objcetMapBean.searchCrewParam.staffNum}": Property 'staffNum' not readable on type java.lang.String
please help me out from this small error .. I am new to jsf so stucking at things basic ...
Thanks in advance :-)
This is my backing bean...

This question already has an answer here:
How to send form input values and invoke a method in JSF bean
(1 answer)
Closed last month.
I have a problem as I mentioned in the topic title. I want to pass the values from two different <h:inputText/> elements as parameters to a method that takes two parameters in Java and send the result to a single <h:outputText/> element. I don't know how to do this.
For this problem, I created the setter and getter methods separately on the CDI Bean to represent both <h:inputText/> elements. Sample codes are as follows.

Creating master-detail pages for entities, how to link them and which bean scope to choose
(2 answers)
Closed 6 years ago.
I've got a datatable with values in which I get from my DB.
In my class myBean, I've got an Variable of type User to store the selected row. It just can be selected one row. Now I want to call this Variable from an other bean which is called printUser to get the selected User.
But it always prints null.
View

rowKey="#{user.id}" >

<h:outputText value="#{user.firstname}" />
</p:column>
<p:column width="250" headerText="Lastname">
<h:outputText value="#{user.lastname}" />
</p:column>
</p:dataTable>
myBean
#Named(value = "myBean")

public class myBean implements Serializable {
private static final long serialVersionUID = 1L;
private User selectedUser = new User();
public myBean() {

}
public Patient getSelectedUser() {

public void setFirstname(String firstname) {
this.firstname = firstname;

public void getSelectedUserData(){
myBean bean = new myBean();
User user = new User();
user = bean.getSelectedUser();
System.err.println("UserID: " + user.getID());
}
}
Hope you undertand my Problem.
Thanks alot
Excuse my English
This is an example to use the entity of the selected row in the same page and in another page. The example use Lombok Getter,Setter and Data annotations for shortness:
The entity for the DataTable:
#Entity
#Data
#TableGenerator( name = "GEN_TestEntity1", table = "ID_Generator", pkColumnName = "GEN_KEY", pkColumnValue = "GEN_TestEntity1", valueColumnName = "GEN_VALUE" )
#NamedQuery( name = TestEntity1.QUERY_ALL_TESTENTITY1, query = "SELECT te1 FROM TestEntity1 te1" )
public class TestEntity1 implements Serializable
{
public static final String QUERY_ALL_TESTENTITY1 = "query_All_TestEntity1";
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue( strategy = GenerationType.TABLE, generator = "GEN_TestEntity1" )
private int id;
#Column
private String name;
}
The ManagedBean as a controller:
#ManagedBean
#SessionScoped
public class EntityBean
{
#EJB
private EntitySER entitySER;
#Getter
#Setter
private TestEntity1 selectedEntity;
public List<TestEntity1> getAllTestEntity1()
{
return entitySER.getAllTestEntity1();
}
public void onRowSelect( SelectEvent event_ )
{
}
}
Another ManagedBean which uses the first one (if you really want it):
#ManagedBean
#RequestScoped
public class AnotherBean
{
#ManagedProperty( value="#{entityBean}" )
private EntityBean entityBean;
...
}
The stateless session bean:
#Stateless
#LocalBean
public class EntitySER
{
#PersistenceContext
private EntityManager em;
public List<TestEntity1> getAllTestEntity1()
{
Query q = em.createNamedQuery( TestEntity1.QUERY_ALL_TESTENTITY1 );
return q.getResultList();
}
}
The index page (index.xhtml):

Since you use ui:define, I assume there is a ui:include in your template file (pagesTemplate.xhtml).
If so, that is great, but your included page has some unnecessary stuff, e.g. html and body tag (by the way: use h:body). No need for that.
See second part of this posting to learn how to include an xhtml file into another one.
You will notice that the content of ui:define is kind of "cut&pasted" into the your template file.
So, what about your form tag? It's being ignored (at least, I guess it won't be a parent of your datatable).
Make the h:form (again, use JSF's h:form instead of HTML form) a child of ui:define,
like:
<ui:composition template="/WEB-INF/template.xhtml"
xmlns=.....>
<ui:define name="content">
<h:form>
<p:dataTable ...>
...
</p:dataTable>
</h:form>
</ui:define>
</ui:composition>
Mojara 2.1.21
I'm using primefaces editor component p:editor. The value attribute in editor is a complex EL-Statement.
<h:form>
<p:datatable value="#{bean.getItems}" var="item">
<p:column>
<p:editor value="bean.A(item).value" />
</p:column>
</p:datatable>
</h:form>
class Bean {
public Entity A (Item i) { return ...}
}
class Entity {
public String getValue();
public void setValue(String);
}
The getter Entity.getValue() is called, but the setter Entity.serValue(String) is not called, if form is submitted.
I suppose it has nothing to do with editor but a common feature of EL. How can I instruct the editor to call a setter if some changes will be made in editor by a user ?
UPDATE
The variant <p:editor value="#{multiEditorBacking.eval(editor).text}" id="textArea" /> has trouble if setter will be called. But <p:editor value="#{editor.text}" id="textArea" /> is ok. The following examples can be used for testing.

This works for me, in Mojarra 2.2.5, using EL 2.2. Are you sure you've got that EL version enabled which allows method parameter passing? You need a Servlet 3.x container available (such as Tomcat 7) or you'll need to add the library yourself. However, it seems you've got it as #{multiEditorBacking.eval(editor).text} value for your editors is being properly evaluated.
By the way, your <ui:composition> surrounding <h:head /> and <h:body /> is unecessary. Another thing I don't like from your code is the use of #SessionScoped for pure view matters. Go with #ViewScoped unless you're explicitly dealing with session related stuff.
#SessionScoped
#Named

Using EL 2.2 with Tomcat 6.0.24
The solution was to use brackets in EL to get setter called.
<p:editor value="#{(multiEditorBacking.eval(editor)).text}"
id="textArea" />
