Why do plex auto convert my list to string

I write this code
`@handler(PREFIX, TITLE, thumb=ICON, art=ART)
def MainMenu():
oc = ObjectContainer()
content = HTTP.Request(BASE)
page = HTML.ElementFromString(content)
group_category = page.xpath(’//li/a[starts-with(@href, “http://www.phim.media/tim-kiem-phim-the-loai-”)]/text()’)
oc.add(DirectoryObject(key=Callback(Group, title=u’Thể loại’, items=group_category), title=u’Thể loại’, thumb=R(ICON)))
return oc

@route(PREFIX + ‘/Group’)
def Group(title, items):
oc = ObjectContainer(title1=u’Danh sách phim’, title2=title, art=ObjectContainer.art)
for item in items[‘items’]:
oc.add(DirectoryObject(key=Callback(Page, title=item, page=1), title=item, thumb=R(ICON)))

return oc

`
I’m sure that group_category is a list ob string by accessing group_category’s elements.
However, when callback happen, the variable items I have in the Group function is type of ‘str’.

Hi again,
the callback is executed as http-call - so the parameters must be strings. To “feed” your function Group you can

  1. use a url and build the list via xpath in function Group or
  2. use a Dict to store the list, pass the Dict-key to the Callback and restore the Dict in function Group, e.g.:
...
content = HTTP.Request(BASE)
page = HTML.ElementFromString(content)
Dict['group_category'] = page.xpath(...).
oc.add(DirectoryObject(key=Callback(Group, title=u'Thể loại', key='group_category'), title=u'Thể loại', thumb=R(ICON)))
return oc

@route(PREFIX + '/Group')
def Group(title, key):
oc = ObjectContainer(title1=u'Danh sách phim', title2=title, art=ObjectContainer.art)
items = Dict[key] 
for item in items:
oc.add(DirectoryObject(key=Callback(Page, title=item, page=1), title=item, thumb=R(ICON)))
return oc

/R
