wawtail rawhtmlblock错误？

Question

我正在尝试测试wagtail RawHTMLBlock，这是我的代码（models.py）：

from __future__ import absolute_import, unicode_literals
from wagtail.wagtailcore import blocks
from wagtail.wagtailcore.fields import StreamField
from wagtail.wagtailcore.models import Page
from wagtail.wagtailadmin.edit_handlers import FieldPanel


class HomePage(Page):
    body = StreamField([
        ('raw_html', blocks.RawHTMLBlock()),
    ])

    content_panels = Page.content_panels + [
        FieldPanel('body')
    ]

现在我正在尝试添加一个HomePage并在我的网站的管理部分添加一些html到body，但我不能这样做，因为我在chrome's控制台中得到这个js错误：

stream.js:87 Uncaught TypeError: Cannot read property 'initializer' of undefined
    at Object.onInitializeMember (stream.js:87)
    at postInsertMember (sequence.js:95)
    at Object.self.insertMemberAtStart (sequence.js:196)
    at Object.onChooseBlock (stream.js:140)
    at HTMLButtonElement.<anonymous> (stream.js:60)
    at HTMLButtonElement.dispatch (jquery-2.2.1.min.js:3)
    at HTMLButtonElement.r.handle (jquery-2.2.1.min.js:3)

wangtail版本是1.13.1，任何想法？

StreamFields需要使用StreamFieldPanel，而不是FieldPanel。

from wagtail.wagtailadmin.edit_handlers import StreamFieldPanel

# ...
    content_panels = Page.content_panels + [
        StreamFieldPanel('body')
    ]
