Ok, I tried the retrieve_javascript-function as well as a simple
javascript-property.
So my widget looks like this:
class TagInputWidget(Widget):
template = """
<input xmlns="http://www.w3.org/1999/xhtml";
xmlns:py="http://genshi.edgewall.org/";
type="text"
name="name"
/>
"""
javascript = [JSSource("""
alert("huhu");
""")]
But this gives me the error
File
"/Users/deets/Projects/privat/TurboGears/Versions/TG11/lib/python2.5/Genshi-0.4.4-py2.5.egg/genshi/input.py",
line 41, in ET
tag_name = QName(element.tag.lstrip('{'))
AttributeError: 'Stream' object has no attribute 'tag'
Any idea what's going on here?
