PrimeFaces LazyDataModel#load() method not invoked anymore after adding OmniFaces - jsf

Question

PrimeFaces LazyDataModel worked before adding OmniFaces jar into pom.xml.
It invokes load() method of LazyDataModel.
LazyPostDataModel.java
public class LazyPostDataModel extends LazyDataModel<Post> {
private PostService postService;
private PostCriteria postCriteria;
public LazyPostDataModel(PostService postService, PostCriteria postCriteria) {
this.postCriteria = postCriteria;
this.postService = postService;
}
#Override
public List<Post> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,Object> filters) {
//other process
}
}
I just add the following dependency into pom.xml for OmniFaces. It does not invoke load() method .
<dependency>
<groupId>org.omnifaces</groupId>
<artifactId>omnifaces</artifactId>
<version>2.2</version>
</dependency>
post.xhtml
<h:form id="postTableForm">
<p:inputText value="#{ManagePostActionBean.postCriteria.name}"/>
<p:commandButton value="Search" action="#{ManagePostActionBean.search}" update="postTable"/>
<p:outputPanel id="listPanel">
<p:dataTable var="post" value="#{ManagePostActionBean.postDataModel}" id="postTable"
paginator="true" style="width:100%;" lazy="true"
rows="10"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="10, 20, 30, 40, 50, 100" rowIndexVar="index">
<p:column headerText="No" style="width:50px;">
<h:outputText value="#{index + 1}" />
</p:column>
<p:column headerText="Name">
<h:outputText value="#{post.name}" />
</p:column>
<p:column headerText="Description">
<h:outputText value="#{post.description}" />
</p:column>
</p:dataTable>
</p:outputPanel>
</h:form>
ManagePostActionBean.java
#Named(value = "ManagePostActionBean")
#ViewScoped
public class ManagePostActionBean {
#Inject
private PostService postService;
private LazyDataModel<Post> postDataModel;
private PostCriteria postCriteria;
public void onLoad() {
System.out.println("ManagePostActionBean Init....");
postCriteria = new PostCriteria();
postDataModel = new LazyPostDataModel(postService, postCriteria);
}
public LazyDataModel<Post> getPostDataModel() {
return postDataModel;
}
public PostCriteria getPostCriteria() {
return postCriteria;
}
public void setPostCriteria(PostCriteria postCriteria) {
this.postCriteria = postCriteria;
}
public void search() {
resetPagination();
postDataModel = new LazyPostDataModel(postService, postCriteria);
}
}
my environment is

Answer 1

You're using TomEE 1.x, which ships with JSF 2.1 (Apache MyFaces).
OmniFaces 2.2 requires JSF 2.2.
You have 2 options:
Downgrade to OmniFaces 2.1. Even though OmniFaces 2.x officially requires JSF 2.2, OmniFaces versions 2.0 and 2.1 do not have deploy time JSF 2.2 dependencies. OmniFaces version 2.2 was with <o:viewAction> tag the first version to require JSF 2.2 during deploy time.
Upgrade to TomEE 7.x, the first version to implement Java EE 7 and thus inherently JSF 2.2. It's currently only available as M1 release. Final release is expected within months.
