Erreur: Impossible de résoudre le champ <apex: inputField>

Question

Vous essayez d'éditer les champs affichés dans une page Visualforce et je suis novice en matière de codage. Je reçois ce message d'erreur (exemple):

Error: Could not resolve field 'Student_Id__c' from <apex:inputField> value binding '{!att.Student_Id__c}' in page AddAttendee 

Toute aide serait grandement appréciée!

originale, la page de travail:

<apex:page controller="AddAttendee" id="page" showHeader="false"> 
    <c:CCHeader /> 
    <script type="text/javascript"> 
     var count = 0; 
     function funcA() { 
     //debugger; 
      if({!!setCount}){return;} 
      else{ 
       for(var a=0;a<=count;a++){ 
        var divObj = document.getElementById('page:formId:pageBlockId:pageBlockTableclsAttendees:'+a+':attCont'); 
        var child = divObj.children[0]; 
        child.style.textDecoration = 'none'; 
        child.style.color = 'black';

        child.removeAttribute('onmouseover'); 

       } 
       count++;

Answer 1

problème est pas lié à la visibilité du terrain. Le problème est qu'il n'y a pas de champ nommé Student_Id__c sur l'objet Attendee ou que vous avez mal orthographié le nom de l'API du champ. Ou peut-être Student_Id__c est le champ de son Parent. Faites-moi savoir si je ne suis pas clair.
