duplicate collection index if you delete an item and then add a new one #1106
Comments
One solution would be the ability to set the initial_size variable via a data attribute on the widget in php ....
$builder->add(
'nice_email_collection_with_options',
'collection',
array(
'type' => 'email',
'attr' => array('data-collection-initial-size' => 3),
.... then using it in the collection plugin definition $.fn.collection = function (option) {
var coll_args = arguments;
...
if($(collection_id).data('collection-initial-size')){
options.initial_size = $(collection_id).data('collection-initial-size');
} |
Why is this still a problem? Are there any workarounds for this? |
I assume because nobody has fixed it yet |

When using the collection widget, with the mopaboostrap-collection.js you can end up with duplicate indexes which results in either errors when processing the form values, or data going missing.
Easy to reproduce:
You will see that the second and newly created third item will have the same index of [2].
They only way to use the widget in it's current form is to add all the new items you need, and then delete the ones you don't just before saving
