ERROR:
There are no errors in code.But when i am going for a preview of vf page i am getting this error "Incorrect parameter type for subscript. Expected Number, received Text "

 

I'm working with cloud flow designer and having some issues with the Apex class callout. I know I will need to return a List<List<CustomSobject>> from the invocable method in order to process the collection. But I am stuck overcomplicating the code in order to get what I would normally use a List for into the right format to return. I probably need an additional for loop but am not sure of the format. If I only return a List<CustomSobject> the Flow will not be able to process it as a collection returning multiple records. Below is my method, this current version compiles but the flow will throw an "List index out of bounds" error. Nor is it correct, as I want all the elements returned not just the first. Thanks in advance.

@InvocableMethod(label = 'Services Available')
public static List<List<Create_Product__c>> getServices(List<Address__c> addressInput){
    //created to hold return list of lists
    List<List<Create_Product__c>> wrapper = new List<List<Create_Product__c>>();

    //The data set to be returned
    List<Create_Product__c> productsAvailable = [SELECT Product_Code__c, Starting_Price__c FROM Create_Product__c];

    for (Create_Product__c products: productsAvailable ){
        List<Create_Product__c> responseList = new List<Create_Product__c>();

        responseList[0].Product_Code__c = products.Product_Code__c;
        responseList[0].Starting_Price__c = products.Starting_Price__c;

        wrapper.add(responseList);
    }

    return wrapper;
}

 

I have a custom object "Service Agreement". I need a button on the opportunity page to create a new "Service Agreement". This seems like it should be pretty simple, but I am not having any success (possibly due to my lack of experience with coding).

Hi All,

I was writing a sample code on Nested List. 
public class NestedListDemo {
    List<String> toDoList  = new List<String>{'laundry','shopping'};
    List<String> laundryList = new List<String>{'lights','darks'};
    List<String> groceryList = new List<String>{'fruits','vegetables'};
    List<List<String>> completeList = new List<List<String>>();
    completeList.add(toDoList);
    completeList.add(laundryList);
    completeList.add(groceryList);
    System.debug('Contents of toDoList'+toDoList);
    System.debug('Contents of groceryList'+groceryList);
    System.debug('Contents of laundryList'+laundryList);
    System.debug('Contents of completeList'+completeList);
    System.debug('Contents of First Element in completeList'+completeList[1]);

}

I am getting error in line 9. Error "Error: Compile Error: unexpected token: ')' at line 9 column 29".
any help would be appreciated.
Thanks in Advance
