[Grok-dev] template issue with WidgetTemplate of megrok.z3cform.base

I'm declaring a widget template like this:

import megrok.z3cform.base as z3cform 

class DictDisplayWidgetTemplate(z3cform.WidgetTemplate):

Starting my server however results in this traceback:

line 71, in execute
    template = os.path.join(template_path, template)
  File "C:\Python26\lib\ntpath.py", line 73, in join
    elif isabs(b):
  File "C:\Python26\lib\ntpath.py", line 58, in isabs
    return s != '' and s[:1] in '/\\'
zope.configuration.xmlconfig.ZopeXMLConfigurationError: File
"D:\Git\QCPython\ART\Server\parts\etc\site.zcml", line 4.2-4.28
    ZopeXMLConfigurationError: File
"d:\git\qcpython\art\server\src\arts\configure.zcml", line 11.2-11.27
    TypeError: 'in <string>' requires string as left operand, not tuple

apparently, the 'template' parameter that is given to the execute method in
megrok.z3cform.base's meta.py is a tuple containing ('arts.browser.widgets',
'widgets_templates/dict_display.pt'), and not a string.

I could solve this by adding

        if isinstance(template, tuple):
            template = template[1]

to megrok.z3cform.base's meta.py

However, I think I'm doing something wrong in the first place: perhaps
grok.template is not the way to do this?
