Error: "Factory Method ... with a void return type must have an associated @Out/Databinder"

[poschd]

Hi everyone,

the following piece of code causes the error 'Factory Method "somethings" with a void return type must have an associated @Out/Databinder' to be displayed. However, in my opinion there's nothing wrong. Actually, everything works. Is this an expected behavior?

Best Regards, Daniel

@Name("somethingManager")
@Scope(ScopeType.CONVERSATION)
public class SomethingManager implements Serializable {
    @DataModel("somethings")
    @Out
    private List<Something> somethingList;

    @DataModelSelection
    @Out(value = "something", required = false, scope = ScopeType.SESSION)
    private Hardware selectedSomething;

    @Factory(value = "somethings") // !Error is displayed right here!
    public void findSomething() { //...
    }
}

Hi Daniel,

This is a bug. I've created an issue  https://jira.jboss.org/jira/browse/JBIDE-6176

You can desable this validation rule in Preferences -> JBoss Tools -> Web -> Seam -> Validator -> Factories -> Unknown factory name. Or switch it to "warning" instead of "error".

Thank you!

Hi Alexey,

thank you for creating the issue and presenting a workaround.

Using the given bean (that I posted above) in a JSF DataTable raises a warning, too. In my application I use RichFaces:

<rich:extendedDataTable value="#{somethings}" var="sth" rendered="#{not empty somethings}">
     <rich:column sortBy="#{sth.id}" label="Some Id">
          <f:facet name="header">Some Id</f:facet>
          <h:outputText value="#{sth.id}"/> <!-- WARNING: "id" cannot be resolved -->
     </rich:column>
</rich:extendedDataTable>

Is this a separate issue or is it tied to [#JBIDE-6176]?

This is the same bug.
