This method added to DataManagers.py seems to fix it. def _PropertySheetsFor(self, client): """Return a (possibly empty) list of PropertySheet objects for client""" # Note: this could include duplicate sheets if persistent sheets # are defined by more than one provider! sheets = () for ob in self._uniqueProviders(('sheets',)): sheets=sheets+ob._PropertySheetsFor(client) return sheets I'm not sure about the semantics of this though. With this method added, when a specialist is asked _PropertySheetsFor, it looks in its own plugins only. It does not look in any of its Racks. I guess it'll do for now. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

WHat your question is, probably, is whether you can you wysiwyg HTML editors with Zope. Some minor inconveniences aside that mostly have to do with file extensions, the answer is yes. As Zope speaks ftp and WebDAV and a host of other protocols, you can easily prepare Zope content with tools like HomeSite and Dreamweaver (and many other tools). Just try it out on a Zope installation hth Rik

This seems to be a pcgi (Zope) error though. Only used it on NT4 and IIS4 but from the above a basic incompatibility seems unlikely (to me). Rik

Re: ZPatterns.. Property sheets... once and for all. ;-)
by Steve Alexander 24 Aug '00

Steve, Ok, it is a bug in manage_tabs. Here's a proper fix: <dtml-if manage_options> <dtml-with "_(option=manage_options[a_])"> <dtml-if "option.has_key('help')"> <td align="right" valign="top"> <dtml-var "HelpSys.button(HelpSys, REQUEST, product=option['help'][0], topic=option['help'][1])"> </td> </dtml-if></dtml-with></dtml-if> Replace the <dtml-comment> with <dtml-if manage_options> and </dtml-comment> with </dtml-if>. I'm putting this in the Collector. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Steve, I don't know what the problem is, but I have a temporary fix. The problem is something to do with providing a "help" button. In lib/python/App/manage_tabs.dtml, at around line 148, comment out this entire dtml-with block: <dtml-with "_(option=manage_options[a_])"> <dtml-if "option.has_key('help')"> <td align="right" valign="top"> <dtml-var "HelpSys.button(HelpSys, REQUEST, product=option['help'][0], topic=option['help'][1])"> </td> </dtml-if></dtml-with> -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

ZPatterns.. Property sheets... once and for all. ;-)
by Steve Spicklemire 24 Aug '00

24 Aug '00

Hi Folks, OK.. I didn't hear much from my last plea for advice... I thought perhaps such a concrete problem would product lots of sage advice... but there's good news: here's another chance! Really Really Basic: If I have a class like so: class Shopper( OFS.SimpleItem.Item, ZPatterns.DataSkins.DataSkin, Acquisition.Implicit, AccessControl.Role.RoleManager, ): """ A Shopper """ # Specify a name for the item type: meta_type='Shopper' and let's say I define some attributes in the class.... id = 'default' email = '' _passwd = '' Now... let's further say that I want a developer using this class to be able to add propertysheets to instances of this class after I'm finished... to make customized versions of these objects. Also.. perhaps I want to take advantage of the 'automatic' nature of property sheets to provide a usable interface so that users can edit various properties. I was successful in adding a propertysheet using the /specialist/anobject/propertysheets/manage_addPropertySheet?id=foo&ns= technique.. which I'm pretty sure I could also implement programattically. ;-). But when I try: /specialist/anobject/propertysheets/foo/manage I get an attribute error looking for 'a_'. I get the same error when I try: /specialist/anobject/propertysheets/foo/manage_addProperty?id=blah&value=hh&type=string Any idea what's up with that? But no matter... I can't add 'email' to *any* propertysheet, even those in the ZClass, since it's already used in the class. So do I leave it out of the class and "hope" that someone defines it in some propertysheet somewhere? Do I do lots of: if hassattr(self, 'email') and so on.. in case somehow it didn't get taken care of? I *know* I missing something deep. I'm sure I'll say something dumb enough here soon.. and someone will point out my basic misunderstanding. ;-) thanks! -steve

Saw this linked from Slashdot. http://oss.software.ibm.com/developerworks/opensource/sashxb/wde_screenshot… I can see it being really nice for Zope -- custom user-interfaces, over the web, with a ZServer backend :-) -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Ability for such simple and trivial things as my patches ? Experience ? Eh... Sorry but this eventually would was true 20 years ago when I'd started my adventure with programming of stupid computers :) How you think ? What is my motivation to produce patches etc ?. Answer is very simple... >Maybe this would help filter down the >collector or at least give anotehr way that it could be prioritised? What way ?. It was a little bug and inconsistence it tree tag and I dont see any better way then very simple and safe (without any influence for compatibility) patch.
