Ordering buttons doesn't appear in nested sequences

[tonthon]

The following Form Schema

import colander
import deform

class Comment(colander.MappingSchema):
    content = colander.SchemaNode(colander.String())

class Comments(colander.SequenceSchema):
    comment = Comment()

class Line(colander.MappingSchema):
    label = colander.SchemaNode(colander.String())
    comments = Comments(widget=deform.widget.SequenceWidget(orderable=True))

class Lines(colander.SequenceSchema):
    line = Line()

class FormSchema(colander.Schema):
    lines = Lines()

form = deform.Form(FormSchema())

If we initialize the form with one line containing multiple comments, the deformOrderbuttons will not appear.
This is due to the way we retrieve the buttons in deform.processSequenceButtons

// Here we collect the deformSeqContainer of the nested sequence
var $ul = oid_node.find('.deformSeqContainer'); 
var $lis = $ul.find('.deformSeqItem');
...
$lis.find('.deformOrderbutton')

A fix could be

// Only list containers that are not nested in a sub-sequence
var $ul = oid_node.find('.deformSeqContainer:not(.deformSeq .deformSeqContainer)');
// Only the container's children that are not nested in a sub-sequence
var $li = $ul.find('.deformSeqItem:not(.deformSeq .deformSeqItem)');

Still want to PR?

I try too if I find some time, probably not before january.
I'd be glad to participate to the deform "revival" :)

For me it has been fixed with the following modifications
