Hello, Previously I made a DTML method that when used within a DTML Document would modify properties on that document. Having this floating around in root made it visible to the whole site, but seemed 'unclean'. So, I attempted to make the DTML method into a ZClass, and making the index_html method in the ZClass contain the exact same DTML as the method... But it doesn't work. So, I tried again - this time with as simple a method as possible, a very basic counter. The DTML method I made in root increments and displays the 'z_count' property on the page that calls it, and creates the property if it doesn't exist, so using it is as simple as: <dtml-var mycount> However, I place the DTML into a new class, and then make a new instance of the class, and it wont work as above. I now have to do this: <dtml-with MyZCCount> <dtml-var MyZCCount> </dtml-with> And, instead of modifying the property of the calling document, it modifies the parent folder's properties. Below is the DTML, can someone please explain what I need to do to get this to work on the calling DTML document instead? If I can't get this simple counter to work I'm going to go mad, since changing properties is something I need to be able to do from many of my planned ZClasses... Thanks in advance! <dtml-if "hasProperty('z_count')"> <dtml-var "'%06d' % (z_count + 1)"> <dtml-call "REQUEST.set('z_count', z_count + 1)"> <dtml-call "manage_changeProperties(REQUEST)"> <dtml-else> <dtml-call "manage_addProperty('z_count', 1, 'int' )"> 000001 <dtml-if>
