It seems your are right. I have to apply the filter-method only on one
template. The following minimal example produces the error:
class WikiSystemsInterface(Component):
implements(ITemplateStreamFilter)
# ITemplateStreamFilter methods
def filter_stream(self, req, method, filename, stream, data):
if not (filename == 'wiki_view.html' or 'wiki_edit.html'):
return stream
req_path = req.path_info
if req_path.startswith(r'/wiki/mitarbeiter'):
ticket_list = tag.fieldset(id='tickets')(tag.legend
(u'Ticketstatus'), format_to_html(self.env, Context.from_request(req),
"[[ProgressMeter(owner=$User)]]"))
stream = stream|Transformer('//d...@id="content"]').prepend
(ticket_list)
return stream
However changing
if not (filename == 'wiki_view.html' or 'wiki_edit.html'):
to
if not (filename == 'wiki_view.html'):
works and now i'm using two different ITemplateStreamFilter.
Thanks for your help.
