Hi, I've run into a bug with <dtml-try/except> with Zope 2.2.0b3. I have a folder called 'root' that looks like this: one (folder) two (folder) three (folder) a_one (dtml method) a_two (dtml method) index_html (dtml method) index_html looks like this: <dtml-try> <dtml-var "_.getitem('a_%s' % id, 1)"> <dtml-except KeyError> Here goes default information. </dtml-try> The idea is to do the following: http://.../root/one --> invoke root/a_one http://.../root/two --> invoke root/a_two http://.../root/one/two --> invoke root/a_two http://.../root/two/one --> invoke root/a_one http://.../root/three --> "Here goes default information." http://.../root --> "Here goes default information." I'm rendering the folders under root (one, two, three, ...) with <dtml-tree>; I want to reconfigure my tree easily while keeping the leaves' content in one place, i.e., in a_one, a_two, etc. in root. The above works with Zope-2.1.6 but not with Zope-2.2.0b3. Here's the traceback: Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: unexpected keyword argument: error_type Traceback (innermost last): File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\pkg\Zope220b3\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\pkg\Zope220b3\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: index_html) File C:\pkg\Zope220b3\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: index_html) File C:\pkg\Zope220b3\lib\python\OFS\DTMLMethod.py, line 167, in __call__ (Object: index_html) File C:\pkg\Zope220b3\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: index_html) File C:\pkg\Zope220b3\lib\python\DocumentTemplate\DT_Try.py, line 212, in render File C:\pkg\Zope220b3\lib\python\DocumentTemplate\DT_Try.py, line 244, in render_try_except File C:\pkg\Zope220b3\lib\python\DocumentTemplate\DT_Util.py, line 262, in namespace TypeError: (see above) Traceback says the problem is at DocumentTemplate.DT_Util.namespace(). The 2.1.6 and 2.2.0b3 implementations are different. Plugging in 2.1.6's code fixes _this_ problem: def namespace(self, **kw): """Create a tuple consisting of a single instance whos attributes are provided as keyword arguments.""" #return apply(self, (), kw) # XXX ngps - following is the 2.1.6 implementation r=namespace_() d=r.__dict__ for k, v in kw.items(): d[k]=v return r, Cheers. -- Ng Pheng Siong <ngps@post1.com> * http://www.post1.com/home/ngps
