Thank you Laurie,

I hadn't gotten a response yet, and yours is more informative. But still,. what I was asking for (and hoping for) is a complete code example of the entire method, not just a list of steps of what I need to do inside of it. Can you pass on a complete code example?

Also -- am I overriding TWO methods, or just one? I can think of one method needed to display the form (and populate the fields if this is "edit" instead of "add"), and another method to accept the form and populate the database.

I was just asking for a complete code example of the method, or both methods as the case may be.

Thanks,

Bryan

Hi Bryan - sorry if you have this solved by now - but I didn't see any reply to the mail below.
What Chris is trying to say (I think) is that within the ZClass that you created, you need to create a dtml method that allows you to edit the properties of your ZClass. 
Here's what I usually do:
---I copy the add form I use to add a new instance and paste it inside the ZClass object (in Products folder). (I tend to call mine index_edit_html). 
---Inside this dtml method, I set the properties of the various text boxes, select lists etc to the values of the instance of the zclass.
---In the same place as where you copied the form you just created create another method (I call mine ZClassName_Update).
---Inside this method call the two functions that Chris mentioned 
e.g. 
    <dtml-call expr="propertysheets.Basic.manage_changeProperties(REQUEST)">
    <dtml-call expr"reindex_object()">

hth,
Laurie

OK Chris,

I understand what you're saying. But my follow-on question is, where exactly can I find the code that is auto-generated from the properties interface? And if there is no such code, then is there a complete code sample, somewhere, of how I would code this myself? Your statement:

You need to create a custom properties-editing form with a target that calls reindex_object as well as modifying the properties." 

isn't really enough for a newbie like me to pick up and run with.

I'm also unclear where this prebuilt form is being built -- is it when I define the property sheet, or instead is it when I create a view out of a property sheet?

Having fun getting to know this system!

Bryan

Hi Bryan,

Please keep the mail on the maillist, thanks.

This is a limitation when using prebuilt forms from the properties 
interface.  The prebuilt propertysheet editing forms don't call 
reindex_object.

You need to create a custom properties-editing form with a target that 
calls reindex_object as well as modifying the properties.

You could make the target a Python Script or a DTML method, as long as 
it calls the right stuff (manage_changeProperties and reindex_object) on 
itself with the right values.

HTH!
