Sending a list of objects from view to controller : limited to 256 objects

I've got a form in my view which send objects to my controller, but the matter is that I've got an exception if I send more than 256 objects : ``` org.springframework.beans.InvalidPropertyException: Invalid property 'followers[256]' of bean class [org.myec3.portalgen.plugins.newsletter.dto.FollowerFileDto]: Index of out of bounds in property path 'followers[256]'; nested exception is java.lang.IndexOutOfBoundsException: Index: 256, Size: 256 ``` So I was wondering why such a limit, and I found this topic : https://stackoverflow.com/a/24699008/4173394 But it doesnt seem to work for me (probably a bad use from me). Here is my structure : My view is called createUpdate.vm and post my form like this : ``` <form id="createFollowerFileForm" method="post" action="#route("followerFileController.upsertFollowerFile")" enctype="multipart/form-data" class="form_styled"> ``` My function upsertFollowerFile in FollowerFileController : ``` @InitBinder public void initBinder(WebDataBinder dataBinder) { // this will allow 500 size of array. dataBinder.setAutoGrowCollectionLimit(500); } @Secured({ "ROLE_SUPER_ADMIN_PORTALGEN", "ROLE_CUSTOMER_PORTALGEN", "ROLE_ADMIN_PORTALGEN", "ROLE_WRITER_PORTALGEN" }) public String upsertFollowerFile( @ModelAttribute(value = "followerFile") FollowerFileDto followerFileDto, BindingResult result, ModelMap model, HttpServletRequest request) { ``` And my class FollowerFileDto : ``` public class FollowerFileDto { private String title; private Long followerId; private boolean isDeletable; private List<FollowerDto> followers; public FollowerFileDto() { this.followers = new ArrayList<FollowerDto>(); } ``` As you can see in my controller, I tried to set more than 256 allowed objects (500) with the @InitBinder annotation, but it doesnt work at all. The InitBinder function is never called. Did I do anything wrong ? Thanks for you answers ;)
