"browse..." button JS error

[tkimnguyen]

Plone 5.0.8, plone.formwidget.contenttree 1.0.15

The autocomplete function works with the text field, but when I click on the "browse..." button, I get this error in the Chrome (Version 65.0.3325.181 on macOS 10.13.4 Beta) console:

Uncaught TypeError: window.showDialog is not a function
    at HTMLInputElement.<anonymous> (@@oiestudyabroadstudent-controlpanel:3024)
    at HTMLInputElement.dispatch (jquery.js:4670)
    at HTMLInputElement.b.dispatch (plone-compiled.js:7509)
    at HTMLInputElement.r.handle (jquery.js:4338)

My code looks like this:

    widget(state_of_wisconsin_need_based_travel_grant_form=ContentTreeFieldWidget)
    state_of_wisconsin_need_based_travel_grant_form = schema.Choice(
        title=u'State of Wisconsin Need-based Travel Grant Form',
        description=u'select the PDF for this form',
        required=False,
        missing_value=None,
        default=None,
        source=UUIDSourceBinder(portal_type='File')

I can confirm the error on Plone 5.2.1 : JS / CSS files are not in registry.xml (but stil in portal_javascripts / portal_css), and leads to the same error (and non-working "Browse" button).

Note that even if those files are included in registry (I tried) :

• the "Browse" modal does not react well with events (href changes when you try to select a node, ...) --> the JS code also needs to be fixed.
• there is an error with missing node/item_icon in input_recurse.pt
