However, you can lever the REQUEST object for this kind of thing: <dtml-call "REQUEST.set('Size', 'big')"> <dtml-call "REQUEST.set('Size', 'bi')"> <dtml-if "Size=='big'"><h1></dtml-if> Hello. <dtml-if "Size=='big'"></h1></dtml-if> Now, 'Size' is found in the REQUEST object, and there the value of 'Size' can be modified. -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Two things wrong here. First, the Size variable is only visible within the scope of the let tag, so you'll have to close it _after_ the block in which you want to use it. Secondly, what comes after the = sign in the let tag, is either a Zope name (same as in <dtml-var name="xxx">), when you don't use quotes, or a python expression (same as in <dtml-var expr="xxx">) when you do use quotes. In your case, "Size='big'" is interpreted as "Size equals the python expression big", where "the python expression big" means the value of the variable named big. There's your Key Error. In order to assign the string literal 'big' to the variable Size, you'll have to use quotes around the word big, either Size='"big"', or (confirming to the official HTML way of quoting) Size="'big'". With above corrections, you're code should read: <dtml-var standard_html_header> <dtml-let Size="'big'"> <dtml-if "Size=='big'"><h1></dtml-if> Hello. <dtml-if "Size=='big'"></h1></dtml-if> </dtml-let> <dtml-var standard_html_footer> -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Jephte CLAIN has released the following products: - jcNTUserFolder, a product that authenticates users on a NT Domain. The main difference with htrd's product is that roles are given through the web, and impersonation is not used. BEWARE. This is beta for now. Please send you comments - MIMETag patch that add features to the mime tag. - WebImport patch to import files through the web. Following soon: - How to use Zope and IIS together in REMOTE USER mode.

Gennerally, IE is very precise at interpreting the HTTP standard. It is quite probable that your app has an error somewhere that Netscape glosses over. One way to you could diagnose this, is by using a HTTP tracer like TracePlus32 Web Detective (a demo can be downloaded from http://www.sstinc.com/) which will show you exactly what Netscape and Explorer send over the wire, and what answers Zope gives. This is much easier than using a telnet session and typing in your HTTP requests manually. It should at least show you what faulty requests IE sends, and from there interpret how IE comes to the conclusion it should send those requests.

wish list for zope in the new century
by Wei Tao 04 Jan '00

04 Jan '00

sorry for my poor english first :> I search the zope site for "todo list" but find nothing, and i can't catch the whole idea from those reports in "zope bug and feature ... collector". So, I want to discuss it in this maillist :> I rather appreciate Zope, especially the excellent OO design for a dynamic web site. But there are some areas Zope need to improve in order to be real killer in the web application server market: 1. integeration for a good HTML(DTML) WYSIWYG editor e.g. a dreamwaver extesion for zope is rather appreciated ( I am not sure whether dreamwaver is the best, any suggestion ? ) and a better integeration for a good python code editor&debugger(IDLE?) is also rather appreciated. 2. better error report and suggestion For a new babie, current error reports for mistakes in DTML are rather horrible. 3. better apache support Hey, I think ZServer is just fit for developing. Apache is the real world answer. Current support for apache is another shortcoming when comparing to mod_perl, mod_php and mod_jserv >_< 4. a good cache for performance Zope IS slow when load is high. and a good cache mechanism will solve most of the question. And here is my idea: <dtml-cache cache-id condition-for-cache-update> .... blah blah blah ... </dtml-cache> and a similiar function for external method. Two import point: a. A block of a page can be cached in order that the cache is efficient when the page contains, e.g., a counter; b. We only need to cache the most accessible blocks which are also most dynamic; Maybe we can steal some code from Squid :) 5. more killer app based on Zope like squishdot e.g. a good full-function forum based on Zope... Perhaps many people comes to Zope just because of squishdot :> 6. open source for ZEO development It is rather disappointing to see the door and window are closed for ZEO's development :<< 7... your opinion?
