Hello.

I have a VF page that displays 2 lists via the apex:repeat method. The items on the list can be deleted when clicking on a link that invoked the following method:

public PageReference deleteAdditionalCategory(){
        PageReference p = null;
        try{
            String categoryId = ApexPages.currentPage().getParameters().get('CategoryID');
            if(vendorAccountMembershipDetails != null && categoryId != null){
                Category__c c = mapCatList.get(categoryId);
                if(c != null){
                  mapCatList.remove(c.Id);
              	  
              	  Integer lSize = 0;
                  if(addCat != null && addCat.size() > 0){
                  	lSize = addCat.size();
                	for(Integer i=0; i < lSize; i++){
	                	if(addCat[i].Id == c.Id)
	                		addCat.remove(i);
	                		//catList.remove((i+1));
                	}
                  }
                  if(catList != null && catList.size() > 0){
                  	lSize = catList.size();
                	for(Integer j=1; j < lSize; j++){
	                	if(catList[j].Id == c.Id)
	                		catList.remove(j);
                	}
                  }
                  delete c;
                }
            }
            goAction();
        }catch(Exception e){
            ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.ERROR,'Exception - ' +e.getMessage());
            ApexPages.addMessage(msg);
            system.debug('------Exception caught----'+e);
            if(vendorAccountMembershipDetails != null){
                //sendExceptionEmail(vendorAccountMembershipDetails, e);
            }    
        }
        
        return p;
    }

 The problem is, the first list (addCat) gets updated but the second one (catList) doesn't. The difference between the two lists is that addCat contains all additional categories associated with a membership order form while catList contains all additional categories plus the primary category. This way, catList will always be larger by 1.

The error I am getting is: Exception - List index out of bounds: followed by the index number of the item I am trying to remove from the list. Here's the odd part... The method will correctly remove items from the lists if I am removing the item at the end of the list. If I try deleting something in the middle, that's when the exception happens.

Hello.

I need help in getting a VF page controller to access inputField values that are created inside an apex:repeat. I know that when converted to HTML, each of those inputFields has an ID that auto-increments, but I don't know how to get the controller to access those values.

Here is the code snippet from the VF page in question that contains the apex:repeat generated inputFields:
