Hi all, playing around with the creation of ZClasses, I noticed that the examples given in the comments of the contructor method for new ZClasses will partly not work. I have now figured out how to get things going, but I would like your thoughts on this before reporting it. Usually, things that I find are wrong are working smoothly and it was only me who has misunderstood ;-) Here goes: the default constructor method uses the following: <dtml-with "TestClass.createInObjectManager(REQUEST['id'], REQUEST)"> and suggests to change the new instance like this: <dtml-call "propertysheets.Basic.manage_editProperties(REQUEST)"> within the <dtml-with> part. I see two problems with that: 1.) the <dtml-with> should use the 'mapping' attribute. Otherwise, neither 'propertysheets' nor 'REQUEST' are available as used in the example. 2.) Even with the mapping, I get a name error for 'Basics'. This is probably due to the line being an example only. I am not very deep into ZClasses so far, perhaps someone can set me right here. I used the following, which did fine: <dtml-call "manage_changeProperties(REQUEST)"> but changed it to <dtml-call "manage_changeProperties(title=REQUEST['title'])"> so that no random request parameters change unwanted properties.
