Wrong initial collection index

[ro0NL]

Hi,

Im using the bootstrap collection JS asset for a symfony collection form field (which is mapped with a doctrine collection).

The collection is embedded with zero initial elements. When adding an element (the first) it gets index 1. The initial index in the doctrine collection is 0, this way validation errors etc. are not displayed at the correct field but at the 2nd collection field (as that one has index 1) or on top of the form without a 2nd collection field.

When I debug the JS forcing to start index 0 everything works as expected. I changed:
this.options.index[this.options.collection_id] = this.options.initial_size;
to
this.options.index[this.options.collection_id] = this.options.initial_size - 1;

Can you have a look at this?

Same problem here.
I supose that you are using 3.0-beta3.
To fix the bug change the line 108 of mopabootstrap-collection.js by this
options.initial_size = $this.parents(collection_id).find('.collection-items').children().length;
