zClass subobjects
by Phil Harris 02 Sep '99

02 Sep '99

Hi all I just created a class based on a Folder, called MemberFolder, that should restrict users from adding certain types of Product. I went to the sub-objects tab in the zClass and selected the ones I wanted to show. However, when in the management screens for that MemberFolder I get all the Products listed with the ones I selected in the sub-objects tab being shown twice. Is it me or is something broken?

For example, a number of the database adaptors do not, Confera doesn't, and there are others that have been mentioned on this list. Anthony

getting static pages out of zope
by Heiko Stoermer 02 Sep '99

02 Sep '99

Hi, sorry to bug you again, but I don't get any further on this: is there an elegant way to get static pages out of zope? Any ideas? The DTML documents have all their variables stored in properties, so actually it's not a very complex thing. I have thought about using "wget" or so, but the problem is that I only want to save specific files on my harddisk, not the whole system. any ideas will be highly appreciated.

While it might THEORETICALLY be possible to beat the file system, it's also non-portable, a headache, painful and all-together a bad idea. Even Oracle no longer requires this.

cutoff documents using Zope 2 w/ IIS + SSL
by Brian Hooper 02 Sep '99

02 Sep '99

Hi - I have a weird problem which I was wondering if anyone might have seen something like this before - it is kind of specific, in particular using IIS and SSL with Zope 2 on Win32. It seems with certain clients (such as Netscape 4.0x, Mac IE 4, etc.), the very bottom part of pages is being cut off when viewed through IIS, over PCGI. Does this sound like an issue with IIS (either with the ISAPI that's doing SSL, or with IIS itself), with the clients which are viewing it, or some combination of both (maybe, most likely)? Has anyone seen anything like this, or have any suggestions as to how to deal with it? Since ZServer serves out the same pages correctly without any problems, I suspect IIS madness - could it be that IIS is screwing with the headers and making a mess of things (I thought of: maybe it's not returning a correct Content-Length?). Something that seems related - unwanted Authorization dialogs popping up upon accessing the part of the site which is accessed via IIS/SSL/PCGI - is this also likely to be something with screwed HTTP headers? This behavior also seems highly client specific. Any opinions or comments? --Brian Hooper

Unexpected transation using Catalog
by Toby Dickenson 02 Sep '99

02 Sep '99

I have a Catalog which has indexed several properties, and a form where you can enter a property name and a property value. The catalog is searched for objects where the named property has that value. I am searching the Catalog using: <dtml-let content="Catalog.searchResults({index_property:index_value}) "> Unfortunately this search is causing extra transactions to appear in the undo log. This happens on the first search for each pair of parameters, after starting Zope or flushing the cache. Am I doing something wrong, or is this a bug? Thanks, Toby
