Problem with > 1 ZCatalog search on same page
by Jeff Sasmor 28 Jun '00

28 Jun '00

Hi Zopistas- I have problem that I hope that there's an answer to. Perhaps this has been covered on this list already, but I couldn't find it by searching the NIP archives and 800+ results for "ZCatalog" was mind-numbing..... I have two ZCatalog searches on the same page (in the same DTML method). Each has different fields so they have different numbers of results displayed in two tables. This works just fine. What's wierd is that the 'batch_size' code interacts between the two-- if the size of the first table's set of results is < batch size and the size of the second table's results is > batch size then the second table has a "next N results" link. If I click this then the second table dutifully displays the next data set. BUT- the first table just displays the LAST item it had displayed before. >From a quick glance at the way that ZCatalog works, it seems as if this behaviour could be correct; and the batching code in the ZC can't handle more than one set of results associated with a single DTML method. But I am by no means sure of my interpretation of the python code here. Anyone have any insights? TIA, Jeff Sasmor jeff(a)sasmor.com PS. For those Zopistas who are MontyPythonistas: I get to see "Eric Idle exploits Monty Python" tonite (weds 6/28) at Carnegie Hall in NewYawkCity. They promise lumberjacks, etc. This goes on tour to some cities in the US this summer. Bought these tickets months ago so have the 4th Row Orchestra! I hope this is as good as seeing Monty at NYC's Civic Center <dtml-more-years-ago-than-I'd-like-to-admit>. John Cleese stepped on my foot whilst selling albatrosses (?) at that one. But I digress...

RE: [Zope] HTML Editors that recognize DTML (was bastardized form ofXML)

This looks very cool - the HTMl jive, that is. I'm going to mod it some, and get permission from the author to incorporate it into Zope... I'll add some features like search and replace also... >>> -----Original Message----- From: Gidon Friedman [mailto:gidon@stars.ch] Sent: Wednesday, June 28, 2000 6:12 AM To: Jon Franz Cc: zope(a)zope.org Subject: Re: [Zope] HTML Editors that recognize DTML (was bastardized formofXML) > Does anyone know of a good (free!) java applet based text editor?

If there is one, we could mod it to spit its output as > a form post, and hus have a great built-in editor for most browsers... that would be nice, but you would have to build one yourself. Java Swing has an HTMLEditorKit, but i never tried to use it. have a look at: http://www.mokabyte.it/1999/12/htmleditor.htm it explains in italian how to do it (untested). or you could use javascript: http://www.cris.com/~raydaly/htmljive.html Gidon <<<

frame in zope
by kmail＠dolphinsearch.com 28 Jun '00

28 Jun '00

I have been looking through egroups for answers to people problem, but haven't found any to work for me. Soory to bug everyone. Ok here is my problem. I am developing a zope application for our company that has frames in it. Three to be exact; top, right and left. Top never changes, right contains a list returned from a database, and the left need to be updated by click on a href in the right frame, with some data from the right. How is the best way to perform this operation, can I tell a frame to reload a page with a python return statement? Or is it best to use some cookie or varible. Thanks for any help.
