layout: BaseFolder |Subfolder1 Doc1 |subfolder1_1 Doc2 |Subfolder_2 Doc3 I'm using dtml-tree to render this view in frame. The application is a error recovery set of pages, where the first sub-folder is an area, second level is a tool, and third is sub-system. Since all the pages are the same except for the recovery procedure, I stored the procedure in a property of the dtml-document. (there's probably a better way of doing it, but I didn't know how to use a tree with anything but objects) The tree is formed from objects('dtml-document', 'folder'). All the code is stored in dtml-methods in the root folder of the tree, and hence accessible to all areas. The dtml-documents several folders deep need to be edited by others. Since they don't know zope,html and barely Word, I have a method which displays a textarea control and lets them type in the recovery procedures. This procedure is then displayed inside a <PRE> tag. No coding required.... each page also has an edit link. The link is to a method in the top level of the tree. The first dtml-method displays a form to modify the properties. it then calls another method, located in the same top-level folder to actually make the changes. If I simply use <dtml-call "Manage_changeProperties" from the second method, the properties of the first containing folder are modified instead of the document (even though the properties aren't defined there, go figure). So, the call stack is: BaseFolder <-1/2 |Subfolder1 | <-- properties changed here. Doc1 ------- |subfolder1_1 Doc2 |Subfolder_2 Doc3 Original Document -> method 1 -> method 2 (which changes document ). Except it changes the folder instead. No combination of <dtml-with> I've tried today (and believe me, I've tried a *lot*) has given me what I need. For some reason the second method is acquiring the folder instead of the document. I don't know if that's because it's in a tree, the sort order the second call or the frame it's in. The only way I found to get around this is to have the first method call the procedure via HTTP_REFERER and put my modifying code at the top. This works, but I'd like to do some error-checking kinds of things. I appreciate the method explanation - It makes more sense now.

I have a series of pages that changes the attributes of a

dtml-document.

...

For manage_changeProperties to work I need the object ID. Passing in <dmtl-var id> doesn't seem to work because I'm not in the same folder.

Is there any way to get the unique id of an object that I can pass along and use with a <dtml-with> tag?

Hmm, I guess maybe I don't get your intent. Suppose I have a DTML Document, 'has_prop', with a property named 'aProp', currently set to 'XXX'. Its body looks like::

<dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. Property 'aProp' has value <strong><dtml-var aProp></strong>.</p> <dtml-var standard_html_footer>

I have a DTML Method (*not* a document, this is important!), named 'change_prop', which looks like this::

<dtml-var standard_html_header> <dtml-call "manage_changeProperties( aProp='YYY' )"> <dtml-call "RESPONSE.redirect( absolute_url() )"> <dtml-var standard_html_footer>

If I traverse through the DTML Document and then call the DTML Method, Zope does the Right Thing (TM):

URL: http://localhost:8080/has_prop/change_prop

leaves me showing the body of has_prop, whose property 'aProp' is now 'YYY'. I don't have to mess with the id of the document at all. The key is that change_prop, a DTML Method, can't have properties: it uses whatever properties belong to (or are acquired by) its "caller." In this case, the caller is has_prop, so has_prop's properties get changed.

Does that help any?
