[TurboGears] Re: AttributeError: 'list' object has no attribute 'text'

I've done a patch for this problem in turbokid, but it's the old version of the patch that was used by kevin (because I can't remove older attachment in trac).

Working with the new widget code some more...

Something I've noticed while converting all our widgets, if you have a
widget who's outermost tab has a py:strip in it (this is also the tag
that has the xmlns:py in it), you will get a trackback that looks
something like this:

AttributeError: 'list' object has no attribute 'text'


Someone mentioned this on IRC the last week, it seems to be a Kid bug
in pull.py:

       current = self.current
       if current is None:
           current = []

so current can be a list and then they are trying to access:

      current.text

on a list.

Should be an easy fix I guess.

The reason we'd py:strip all those out tags is because of the ugly xmlns:py in 
the output.


That's the actual TextField template:

   template = """
   <input xmlns:py="http://purl.org/kid/ns#";
       type="text"
       name="${name}"
       class="${field_class}"
       id="${field_id}"
       value="${value}"
       py:attrs="attrs"
   />
   """

but as you can see xmlns:py is stripped from the final output:

from turbogears import widgets as w
text = w.TextField(name="name")
text.render()


'<INPUT ID="name" TYPE="text" CLASS="textfield" NAME="name">'

text.render(format="xhtml")


'<input id="name" type="text" class="textfield" name="name"></input>'

what's happening on your output?

Well look at that, you're right.  I could have sworn that it was output
before.
