Problem with looping through EntitySubscription

Question

Im passing an array of Ids from my JS into currentUserId,

JS

    <apex:form > 
        <apex:actionFunction action="{! removeFollower }" name="processId" oncomplete="refresh()">
            <apex:param assignTo="{! currentUserId }" name="userId" value="" />
        </apex:actionFunction>
    </apex:form> 

EXTENSION

   public String[] currentUserId { get; set; }

I want to then loop through EntitySubscription and delete each of them. This method works for single Ids, but I need to edit it to accept multiple Ids.

    public PageReference removeFollower() {         
    try {

        for(Integer i = 0; i<currentUserId.length; i++){
                EntitySubscription subscription = [SELECT parentId FROM 
                                                   EntitySubscription 
                                                   WHERE subscriberId = :currentUserId[i]
                                                   AND parentId = :id];
                Delete subscription; 
           }       
        } catch(Exception ex) {
            system.debug('Error: ' + ex);
        }
        return null;   
    } 

At the moment, I'm getting this error.

Error: Compile Error: Initial term of field expression must be a concrete SObject: LIST<String>

Would anyone have any suggestions or advice?

Answer 1

public void removeFollower() {         
    Database.DeleteResult[] results = Database.delete([SELECT Id FROM EntitySubscription WHERE SubscriberId IN :currentUserId AND ParentId = :Id LIMIT 500], false);
    // process results here
}
