upgrade to 4.3.5 breaks use of OrderedSelectWidget

[petri]

I have a z3c.form with a field defined thus:

extra_products = schema.List(title=u"Choose products", required=False,
                    description=u"Chosen products will be added to each order row.",
                    value_type=schema.Choice(source=ProductSourceBinder()))

As per docs, the default widget for this is the z3c.form.browser.orderedselect.OrderedSelectWidget. This was working fine before upgrade. After upgrading, the widget only shows up & down arrows, but nothing else - nothing to select from, either.

I tried switching back to 4.3.4 and also (on 4.3.5) instead of schema.List switching to schema.Set to change the default widget to regular multi select, and both such "downgraded" cases work fine.

I can confirm this also affects for example ftw.globalstatusmessage, another third-party package apparently using OrderedSelectWidget.

Try downgrading to z3c.form 3.2.1.

The only difference, it seems, from 3.2.1 to 3.2.3 is that some inline javascript was moved into a file.

Can you see if the orderedselect_input.js is getting included in your rendered page? Can you check if there are javascript errors related to it?

orderedselect_input.js is included, yes - no JS errors on Safari on OS X

Downgrading to z3c.form 3.2.1 helps - no problem there.

@pbauer any idea what might be going on? You did the change.
