This is where I am at right now. I wrote a javascript function loadZopeMethod() and I tried it by itself and it works. But I tried what you suggested: tal:attributes="onclick string:showObject(event, '${box}'); jsRoutine2(); jsRoutine3();" <A href="javascript:;" tal:attributes="onclick string:showObject(event, '${box}'); loadZopeMethod();">MACAddress Table</a> This does not work. Did I do something wrong? BTW thanks for your time.

AFAIK javascript can not call a zope method (dtml, script or external method) directly, javascript has to do indirectly by loading a url into the browser. You can load into a window, frame, div, etc. Here is an example: displaywindow.location.href = '<dtml-var baseurl>DisplayPage?id='+presentorpage+'&stype='+pagetype+'&path='+pagep baseurl>ath This one line of javascript will load a zope routine called DisplayPage (with a url path specified by a dtml variable called baseurl) into a browser window named 'displaywindow'. It also passes some parameters (id, stype, path) to the zope routine. If you need to communicate between the client process (running in the users browser) and the server process (ie a zope routine) without the user seeing anything, you can accomplish this using a hidden div in your html (use javascript to load the url (containing your call to the external method) into the hidden div), this will allow you to call a zope routine and get some results without changing the user's browser's display. The zope routine you call (via the hidden div) can return javascript variables which you can then parse to determine what you want to do next (embed an 'onload' javascript command in the html returned by the zope routine to cause a javascript routine to execute after the hidden div is loaded).

That is new for me, it sounds like if ZODB had a global lock for the entire database? I thought locks were more localized inside the object hierarchy tree. Interesting.

ClassSecurityInfo().declareProtected()
by drew nichols 29 Sep '04

Hello, Is it possible to protect a class method with multiple permissions? ClassSecurityInfo().declareProtected(['perm1','perm2'], 'method') doesn't seem to work and ClassSecurityInfo().declareProtected('perm1', 'method') ClassSecurityInfo().declareProtected('perm2', 'method') will default to perm2 - the last assertion. Do I need to create a new permission?

error tb in manager interface
by John Hunter 29 Sep '04

In my stand_error_message, I do <dtml-var error_tb> but this does not seem to apply to errors generated in the manager interface. Is there an analog for manage pages? JDH

Calling external method from javascript
by Laura McCord 29 Sep '04

29 Sep '04

Hi, I am having trouble with this part of my program. I have an onclick function that needs to perform three things. I know that I should have a javascript function that basically handles these three operations, but I don't know how to call an external method from javascript. I am using a zope page template if that helps. I have googled on this topic and there is not a lot said about this situation. I did run across someone using dtml and calling dtml methods from javascript but did not see any examples on using it with zope page templates. Typically I would call a external function like this: <div tal:content="python:here.deleteMAC()"> but this won't work. Thanks in Advance. Laura

How to handle ZODB conflict errors
by aa bb 29 Sep '04

29 Sep '04

Dear Zopistas, I�m using Zope 2.7.0 with installed product ZMS (Content Management from Germany) for our Intranet. Data.fs ist about 117MB, mostly text objects, some pdf. Machine is P4 2,6GHZ, 512MB, Win2000. Sometimes there is considerable delay on delete or save actions, usually corresponding to event.log entries such as: 2004-09-28T10:34:35 INFO(0) ZODB conflict error at /Intranet/content/e14/index_ger.html (8 conflicts since startup) or 2004-09-28T09:32:33 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of /Intranet/content/... Rebuilding the catalog didn�t help as did ZEXPorting the whole to a fresh data.fs. Fsrecover.py did not find any problems. I unsuccessfully tried to find explanations what the first error exactly means. The error_log in the Root directory doesn�t give me clues. Who can tell me what ZODB conflict error exactly means and how it is produced? (web documentation seems to assume everybody knows) Is the problem necessarily caused by the product? Does anybody have a suggestion how to further tackle this? I hope those questions are not too stupid...
