primefaces autocomplete issue

Basically I am trying to do a search of the users on my social network project using autocomplete of primefaces. The problem that I am facing is that whenever a new user signs up, the autocomplete is sometimes showing the new user in the suggestion and sometimes its not showing. Normally during first time a user signs up the autocomplete showing the user's name in the suggestion but the second when another user signs up ,his name is not showing in the suggestion. I think userDB is not getting updated. But whenever I redeploy the project everything is working fine. The name of the user is showing in the autocomplete.

dynamic div gets reset

Volodymyr Levytskyi wrote:Hello!

If you want not to reload your page when command link is clicked and form is submitted (chatBean.refresh is executed) you can use AJAX<f:ajax execute='id1,id2' render='id1,id4'/>.
But if you simply need to hide your div via javascript without executing chatBean.refresh method, you should add 'return false'. Consider this link:
<a href="#" onmousedown="if(document.getElementById('mydiv').style.display == 'none'){ document.getElementById('mydiv').style.display = 'block'; }else{ document.getElementById('mydiv').style.display = 'none'; };return false;">Show more details</a>
To disable page reloading when javascript is executed you should add 'return false'. It must work!

Since I am new to JSF, so it would be helpful if you tell me how I should use the for my code.

dynamic div gets reset

I am trying to display the `chatBean.selectedUser` in the dynamic div that is generated by the javascript when the h:commandLink is clicked. The problem that I am facing is the that the page is refreshed whenever I click the commandLink button due to `action=#{chatBean.refresh}`, so the dynamic div gets reset and I am unable to create the dynamic divs. I need to submit the form to update the selectedUser property, but the form submit resets the page.

1)Here is the xhtml page

getAsObject not called

What I am trying to do is that I am taking timeMillis property that stores time in millisecond(that I got my using `system.currentTimeMillis`) and convert it to equivalent days,hours,mins and seconds after substracting it from the current time.The main problem is that whenever the converter `timeConverter`
is called only getAsString function is invoked , getAsObject is not invoked. I have registered the timeConverter in facesconfig.xml

1)Here is the part of my xhtml file which causing the converter to not run properly.

<c:forEach var="p" items="#{statusBean.statusList}" >
<h:form>
<div class="status">
<h:commandLink action="#{friendBean.gotoFriendProfile(p.email)}"> <img src="../images/profilePicture/#{p.picture}" style="height: 29px; width: 29px; "/> <h:outputText value="#{p.statusBy}:"/></h:commandLink><h:outputText value="#{p.statusmsg}"/><h:outputText value="#{p.timeMillis}"><f:converter converterId="timeConverter"/></h:outputText><br/>
<c:forEach var="q" items="#{statusBean.commentList(p.statusId)}">
<div class="barcomment">
<br/>
<h:commandLink action="#{friendBean.gotoFriendProfile(q.email)}"> <img src="../images/profilePicture/#{q.picture}" style="height: 29px; width: 29px; "/><h:outputText value="#{q.commentBy}:"/></h:commandLink><h:outputText value=" #{q.comment}"/>
</div>
</c:forEach>
<br/>
<div class="comment">
<p:inputText value="#{statusBean.comment.comment}" styleClass="box" />
<p:commandLink value="Views" action="#{statusBean.update(p.statusId)}" ajax="false" styleClass="link"/>
</div>

2)Here is the timeConverter class that I have written.

package com.converter;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
public class TimeConverter implements Converter {
@Override
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
System.out.println("inside getAsObject");
long time=Integer.parseInt(arg2);
long currentTime=System.currentTimeMillis();
long eclapseTime=time-currentTime;
long secs=eclapseTime/1000;
long days=secs/(60*60*24);
long hours=(secs%(60*60*24))/60*60;
long mins=(secs%(60*60*24)%(60*60))/60;
long secs2=(secs%(60*60*24)%(60*60)%(60));
StringBuffer sb = new StringBuffer();
sb.append(days).append("days").append(hours).append("hours").append(mins).append("mins").append(secs2).append("secs");
String object1 = sb.toString();
return object1;
}
@Override
public String getAsString(FacesContext context, UIComponent component,
Object value) {
System.out.println("inside getAsString");
String value1 = value.toString();
return value1;
}
}

Java Heap Space Error due to add function

Whenever I am calling the getFriendList function from the xhtml page I am getting an exception. The page keeps on loading and after that I stop the browser. I get the given stackstrace. Its is telling me that there is an error at line no.78 friends.add(friend); . I think there is something wrong with my syntax. It would be helpful if someone point the error.

1)Here is my FriendBean it is request scoped.

return results;
}
public String friendAccept(String friendRequestId){
System.out.println("friend accept called...");
Friend f=em.find(Friend.class,Integer.parseInt(friendRequestId));
f.setStatus(1);
em.getTransaction().begin();
em.persist(f);
em.getTransaction().commit();
Friend viceversa=new Friend();
viceversa.setEmail(f.getFriendEmail());
viceversa.setFriendEmail(f.getEmail());

Could you please give me an example on how to use the DataModel for obtaining the statusId, Actually I am new to JSF so I don't how the dataModel works

commandButton is fired multiple times.

I am having the exact same problem when I am using dataTable instead of ui:repeat. The problem is that multiple commandLink are possibly getting fired. If I am using dataTable ,suppose there is an inputText and a commandLink inside the datatable and it is repeated four times. So whenever I click the first commandLink associated with the inputText , I get exception four times,comment cannot be null. So I am assuming the commandLink is fired four times. But if I click on the fourth commandLink everything is working fine, the comment field is getting inserted in the database.

commandButton is fired multiple times.

I am trying to comment on status that is retrieved from the database. Whenever I am submitting the comment for specific status I am getting the exception.I have used <ui:repeat> to repeat the commandButtons. I don't know if the commandButton can be put inside <ui:repeat> or not. It would be really helpful if somebody could point out my mistake.Actually what is happening is that whenever I am trying to insert data into the database using '<h:inputText>' other commandButtons created due to using '<ui:repeat>' is possibly getting fired. I have inputText and commandButton inside the ui:repeat tag. So, some of inputText are supposed to be empty because I am selecting one inputText and clicking the corresponding commandButton

1) Here is my xhtml

2)Here is statusBean

package com.bean;
import java.util.List;
import javax.faces.context.FacesContext;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.Query;

import com.entity.Comment;
import com.entity.Status;
import com.entity.User;
public class StatusBean {
Comment comment;
Status status;
private EntityManager em;
public Comment getComment() {
return comment;
}
public void setComment(Comment comment) {
this.comment = comment;
}
public Status getStatus() {
return status;
}
public void setStatus(Status status) {
this.status = status;
}
public StatusBean(){
comment = new Comment();
status=new Status();
EntityManagerFactory emf=Persistence.createEntityManagerFactory("FreeBird");
em =emf.createEntityManager();
}
public String save(){
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
User user = (User) session.getAttribute("userdet");
status.setEmail(user.getEmail());
System.out.println("status save called");
em.getTransaction().begin();
em.persist(status);
em.getTransaction().commit();
return "success";
}
public List<Status> getStatusList(){
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(true);
User user=(User) session.getAttribute("userdet");
Query query = em.createQuery("SELECT s FROM Status s WHERE s.email='"+user.getEmail()+"'", Status.class);
List<Status> results =query.getResultList();
return results;
}
public String update(String statusId){
System.out.println("Update Called...");
comment.setStatusId(Integer.parseInt(statusId));
em.getTransaction().begin();
em.persist(comment);
em.getTransaction().commit();
return "success";
}
}

3)Here is the comment entity class

4) Here is stacktrace that I am getting
