"dataTable" return empty data

 Hello,

I have an problem. I try to use data table apex function in my page, but show me empty always. The controller return good data, but something happens in "apex:dataTable". This is my code:

<apex:page controller="exampleCon" cache="false">
  <apex:dataTable value="{!contacts}" var="c" id="theTable" rowClasses="odd,even" styleClass="tableClass">

        <apex:column><apex:facet name="header">Name</apex:facet>
            <apex:outputText value="-{!c.Name}"/>
        </apex:column>

        <apex:column>
            <apex:facet name="header">Phone</apex:facet>
            <apex:outputText value="-{!c.Phone}"/>

        </apex:column>

    </apex:dataTable>

</apex:page>


And my controller:

public class exampleCon {

    List<Contact> contacts;

    public List<Contact> getcontacts() {
        contacts = [select Name, Phone from Contact limit 10];     
        return contacts;
    }
}


Thanks.

Check whether you have permission to read Contact object and its fields

Hi 

 

You have to use getContacts() instead of getCases.OR You have to change the  datatable value in VFpage to cases instead of contacts. and You have to write  list<Contact> contacts=new list<Comntact>();

I change the function name to getContacts(), but this continue to fail.

Hi 

 

Use list<contact> contacts=new list<contact>(); or you can directly use list<contact> contacts=[select.......]; in get method

 

thanks.

Dont work.

 

If I try to extract information and put is in a variable, work perfectly:

 

I add this in my controller:

 

 

String Phone;

 

 

.......................

 

    public String getPhone() {
    Phone = contacts.get(0).Phone;
    return Phone;
    }

 

 

And in my page:

 

   <apex:outputText value="{!Phone}"/>

 

 

And show me a phone number.

I want to show a list of contacts using  apex:dataTable. I try to say you that do not fail in apex class, fail in the apex page.
