Can Map collection be Apex:Repeat tag 's value ?

Good day,

 

Can i know if Apex:Repeat tag's value able hold Map instead of List ?

 

 

VF page 
------------
<apex:repeat value="{!partnerFieldList}" var="field">   

<apex:variable var="currentLabel" value="{!$Label.first_name}" rendered="{field.containsKey('First_Name__c')}"/>


Controller
-----------
 public Map<String,Boolean> partnerFieldList = new Map<String,Boolean>{			
			 'First_Name__c' => TRUE
			
		};    
 
   public Map<String,Boolean> getPartnerFieldList(){
    	return partnerFieldList;
    } 
 
 
 I would like to rendered the 'firstname' variable if the field are calling, but i get "Unsupported type common.apex.runtime.impl.MapValue encountered."error when i run the apex page
 
Thank you !

Rather than attempting to use a Map as the backing value for the repeat, you would define a subclass encapsulating all the information required of an entry in the Map, and return a List of instances of the subclass.
 
E.g. 
 
 
-- in controller 
  
public List<PartnerFields> partnerFieldList = new List<PartnerFields>();
public List<PartnerFields> getPartnerFieldList()
{
     PartnerFields pf=new PartnerFields();
     pf.hasFirstName=true;
     partnerFieldList.add(pf);
     return partnerFieldList;    
} 
 
  public class PartnerFields  
  {     
      public Boolean hasFirstName {get; set;}
  }
 
-- in VF page 
 
<apex:repeat value="{!partnerFieldList}" var="field">   

<apex:variable var="currentLabel" value="{!$Label.first_name}" rendered="{!field.hasFirstName}"/>

You need to use subclass logic for achieving the same.

Hi , 
 
Do you mind to provide me some sample what you means by subclass logic ?
 
Thank you !

This is pathetic.  Yet add another cheap work around to the big list  of things that should just work out of the box.
