I've got a small thing with ZPT here. My template got a property "activetab", which represents the number of the active tab in the template. This affects mainly the coloring of table headers. My problem is how to change this property by clicking on a link within one of the tabs?! My first thought was to use a script, but how do I tell the script which tab/link was clicked on? Or can I directly change the property by linking to the template?
Do not use a property for this!
Which tab is active is *not* a property of the object but of the visit history.
Encode the information in the URL or in a session. Look at the ZMI for an example (--> "App/dtml/manage_tabs.dtml") how to do this.
Coding "activeness" in the template has 2 serious drawbacks:
* visits by other persons change the object state, I see
* each visit causes the template to be written to the ZODB leading to unnecessary write operations (potential conflict errors) and an unnecessary ZODB growth.
That's right, came to my mind, as I saw my page template this morning. I think I was a bit blind about that. Andreas -- Try to value useful qualities in one who loves you.
