The class does not have property [duplicate]

Question

In my entity:

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(unique=true, nullable=false)
private int tId;
....
public int getTId() {
      return this.tId;
}

public void setTId(int tId) {
      this.tId = tId;
}

And code in my JSF page:

<ui:repeat value="#{techCat.techsOfCat}" var="post">
    <h:outputText value="#{post.getTId()}"/>
        ...
</ui:repeat>

The result is good. But if i code:

<ui:repeat value="#{techCat.techsOfCat}" var="post">
    <h:outputText value="#{post.tId}"/>
    ...
</ui:repeat>

I faced an error:

value="#{post.tId}": The class 'model.Technology' does not have the property 'tId'.

I really don't understand that error. Can you explain to me? Thanks

Answer 1

The error means that correct getters and setters could not be located for your property. The correct syntax for your getter and setter should be:

public int gettId() {
    return tId;
}

public void settId(int tId) {
    this.tId = tId;
}

If you are not sure- always use code generation for your getters and setters.

If you are interested in the specific convention, your getter and setter will relate to TId not tId.
