2.7 workflow not working anymore

Hi there, I have a DCWorkflow (running under plone 1.04) that has bean doing fine now for a year or so. Now under 2.7 I get the following traceback: thanks for any help Robert Traceback (innermost last): Module ZPublisher.Publish, line 100, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module Products.CMFPlone.FormTool, line 235, in __call__ Module Products.CMFPlone.NavigationTool, line 98, in getNextObject Module Products.CMFPlone.NavigationTool, line 289, in _getScript Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module Products.CMFCore.FSPythonScript, line 92, in __call__ Module Shared.DC.Scripts.Bindings, line 261, in __call__ Module Shared.DC.Scripts.Bindings, line 292, in _bindAndExec Module Products.CMFCore.FSPythonScript, line 126, in _exec - __traceback_info__: ({'traverse_subpath': [], 'container': <PloneSite instance at 415a00b0>, 'context': <Image at /intranet/intranetFHA/Members/sorg/Beispiel.jpg>, 'script': <FSPythonScript at /intranet/intranetFHA/object_status_modify used for /intranet/intranetFHA/Members/sorg/Beispiel.jpg>}, ('publishCompany', ' ', '', '', '', None, None, None, []), {}, (None, '', None, None, '', None, None, None, [])) Module None, line 61, in object_status_modify Module Products.CMFPlone.WorkflowTool, line 37, in doActionFor Module Products.CMFCore.WorkflowTool, line 309, in doActionFor Module Products.CMFCore.WorkflowTool, line 624, in _invokeWithNotification Module Products.DCWorkflow.DCWorkflow, line 275, in doActionFor Module Products.DCWorkflow.DCWorkflow, line 440, in _changeStateOf Module Products.DCWorkflow.DCWorkflow, line 489, in _executeTransition Module Shared.DC.Scripts.Bindings, line 261, in __call__ Module Shared.DC.Scripts.Bindings, line 290, in _bindAndExec Module Shared.DC.Scripts.Bindings, line 1, in ?

2.7 management_page_charset cannot be callable anymore
by Martijn Faassen 16 Jan '04

16 Jan '04

Hi there, Some changes in Zope 2.7 break the possibility to make management_page_charset a callable (for instance a method). This breaks Formulator, as it uses this facility. This works just fine in Zope 2.6, but breaks in Zope 2.7. The silly thing is that Formulator 2.6.0 breaks in Zope 2.7 exactly because it actually is the release that tries to do unicode *right* (while still retaining backwards compatibility with older installations and offering a non-unicode mode), and then Zope 2.7 makes it impossible. I heard a report that a similar problem may be occuring with ZWiki.. The problem is in lib/python/App/dtml/manage_page_header.dtml: <dtml-unless management_page_charset> <dtml-call "REQUEST.set('management_page_charset','iso-8859-1')"> </dtml-unless> <meta http-equiv="content-type" content="text/html;charset=&dtml-management_page_charset;"> <dtml-call "RESPONSE.setHeader('content-type','text/html;charset='+management_page_charset)"> If I remember my DTML well, &dtml-management_page_charset; should still call the method if it's a callable, so that would be all right. The next line however breaks, as it's going to treat my method as an attribute. I think backwards compatibility got broken unintentionally here.. Could this be restored? Using a ComputedAttribute for this would be rather involved and it's possible other products are broken as well as a result. Regards, Martijn

win32 setup sources
by Alberto Degli Esposti 16 Jan '04

16 Jan '04

Hi, I need a solution to quickly and easily deploy zope applications on the win32 platform. What I'd like to realize is a setup program that install and configure Zope bundled with all the needed products, making questions to the user for correctly setup the application. Unfortunately I have no experiences in windows programming and related setup tools and I'm lookin for good examples. Can someone tell me something about the win32 Zope installer and the tool used to build the executable? Are the sources available so I can simply customize them? (this is why I've sent the post to this list, please sorry if I'm OT!!) Thanx A.

Zope-2.6.3 issue with CMF-1.3.3 portal_types
by Erik A.Dahl 16 Jan '04

16 Jan '04

I downloaded 2.6.3 to do some testing and found that with a totally generic CMF-1.3.3 there is an issue with opening properties of a portal type. Here is the stack trace: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Products.CMFCore.utils, line 313, in manage_propertiesForm Module Shared.DC.Scripts.Bindings, line 261, in __call__ Module Shared.DC.Scripts.Bindings, line 292, in _bindAndExec Module App.special_dtml, line 174, in _exec Module DocumentTemplate.DT_In, line 703, in renderwob Module DocumentTemplate.DT_Let, line 76, in render Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: select_variable Module <string>, line 0, in ? AttributeError: min I walked back up this stack but I can't say I quite get it. Any body else? Error is provoked just by licking on one of the type objects in portal_types of a newly created totally generic portal. -EAD

[ZConfig] elementary function framework and "env" function
by Dieter Maurer 16 Jan '04

16 Jan '04

We often have the need to use the same configuration value both in a ZConfig configuration as well as in other non-ZConfig based "components". Prominent examples are the "INSTANCE_HOME" in the Zope/ZEO startup scripts and the "INSTANCE" definition in the corresponding configuration files. Moreover, configuration values are sometimes arithmethically related, but ZConfig lacks arithmetic capabilities. An example is the ZEO port which should (under some conditions) be derived from "PORT_BASE". Giving "ZConfig" access to the environment, allows configuration setup to use the arithmetic capabilities of the shell and communicate configuation values via the environment between "ZConfig" based components and components that use different configuration schemes. The attached patch gives "ZConfig" an elementary function framework. An application can register functions with "ZConfig". These functions can be called through "substitution". Its syntax is similar to "gmakes" function call: $(f) calls function "f" with no arguments $(f a1,a2,...) calls function "f" with arguments "a1", "a2", ... Arguments are "," separated, stripped and substitution expanded before they are passed to the function. "," can be escaped through duplication, "(" is not allowed in the "ai" (although they can come up after substitution). Functions are called with "mapping" as additional first argument (such that they can do fancy things; e.g. implement Bash's "default" interpolation ("${name:-default}"). The patch uses the framework to implement a single function "env": env(name, default=None) returns the value of "name" in the environment or "default". If the result it "None", a "KeyError" is raised. -- Dieter

[ZConfig] "redefine" extension
by Dieter Maurer 16 Jan '04

16 Jan '04

It is often favorable to have a set of site wide defines that can occasionally be redefined for special purposes. The attached patch adds a "%redefine" directive to ZConfig's "cfgparser". "%redefine" behaves exactly like "define" but does not check whether the name is already defined. -- Dieter

Hi Robert, > Hi Tres, > Adding 'guarded_hasattr' to the list of items wrapped items did not help. > I guess You have taken Tres too literally. I did the same (i.e. adding the string 'guarded_hasattr' to the _NEED_WRAPPING list) and could reproduce Your issue.

Re: [Zope] Converting a web site

In all cases but one where I have been involved in converting one site to a Zope managed site, the people have scrapped the old site completely, and made a new one from scratch, with a new, improved structure and layout. It involves a lot of copy/pasting text from the old site, sure, but the end resul is better. If you are just to have a bunch of static files, you can just as well just use Apache anyhow. :) And if you don't, there are products that let you store the files on the harddisk, where they are now, accessing them through Zope, but not needing to import them. LocalFS is the most common one, I think.
