I wrote up some code (dated) to present generic forms for changing
zclass properties, code to follow. i generally use it just to get a fast
prototype for a system, example: picking a property sheet and harding
coding a link to the second method. yes this code does find base class
properties (including stuff like webdav, etc), or at least it did last
time i used it (era 2.1.6). 

hope this helps

three methods

one to select a property sheet

one to edit a property

one to change a property sheet


1. edit_properties

<dtml-var standard_html_header>
<center><b>Please Pick A Property Category</b></center>
<table align="center">
<form action="edit_propertyCategory" method="POST">
<tr><td>
	<SELECT name="PropertyCategory">
<dtml-in "propertysheets.items()">
	<OPTION value="<dtml-var sequence-key>"><dtml-var
sequence-key></OPTION>
</dtml-in>
	</SELECT>
</tr></td>
<tr><td><INPUT TYPE="SUBMIT" value="Edit Properties"></td></tr>
</form>
</table>
<dtml-var standard_html_footer>

2. edit_PropertyCategory

<dtml-var standard_html_header>


<dtml-if "REQUEST.has_key('PropertyCategory')">

<dtml-in "propertysheets.items()">
<dtml-let y=sequence-key>

<dtml-if "REQUEST.PropertyCategory==y">
	<dtml-let x=sequence-item>

	<table border="1" align="center" cellspacing="0" cellpadding="4">
	<tr><th colspan="2" align="center">Edit <dtml-var y>
Properties</th></tr>
	
	<form action="edit_propertiesChange" method="POST">
	<dtml-in "x.propertyItems()">
		<tr><td>
		<dtml-var sequence-key>
		</td><td>
		<input type="text" name="<dtml-var sequence-key>" value="<dtml-var
sequence-item>">
		</td></tr>
	</dtml-in>

	<tr><td colspan="2" align="center"><input type="SUBMIT" value="Change
Properties"></td></tr>
	<input type=hidden name="PropertyCategory" value="<dtml-var
