Issue with iterating map in visualforce page. VF page is Not getting save

Question

I have below code in my VF page -

<tbody>
  <apex:repeat value="{!objVsFieldsMap}" var="key" id="theObjReapter1">
     <tr>
       <td>{!key}</td>
       <apex:repeat value="{!objVsFieldsMap[key]}" var="lstVal">
         <td><p>{!lstVal.val}</p></td>
       </apex:repeat>
     </tr>
  </apex:repeat>
</tbody>

And I'm not able to save the VF page. It shows me Syntax error. Found 'objVsFieldsMap'. The strange thing is the same kind of code is working for other VF page. Any idea about it?

Answer 1

You are passing the same key store the ids in set or any other do something like this

public class toda {
Public Map<Id,Account> acc {get;set;}
public set <Id> ids {get;set;}
public toda ()
{
    ids  = new Set<Id>();
    acc = New   Map<Id,Account>([Select Id,Name From Account limit 100]);
 for(Account acc :acc .Values() {
  ids .add(acc.Id);
 }
}} 

Use that Id in place of key
