[Zope] Re: Inserting foldernames into propertysheet 'selection' dropdown

[Gary Duke Speer]

I received a great suggestion that seems to be on the right track,
but I am hitting a namespace issue.
The suggestion was to convert the string of folder ids to a list using
'string split'.
I'm hitting the error "global name 'objectValues' is not defined".

Where I am at:
Propertysheet has property 'selectfolder' of type 'selection' that obtains
it's list from the method 'returnfolders'

DTML Method 'returnfolders' contains
<dtml-return "_.string.split(getfolders(),' ',0)">
to parse the string of space-separated folder names from 'getfolders' into
a list.
By itself, this works.

DTML Method 'getfolders' contains
<dtml-in "objectValues(['folder'])"><dtml-unless hidefolder><dtml-var id>
</dtml-if><dtml-in>
to generate the filtered list of ids.
By itself, this works.

When 'returnfolders' executes 'getfolders' it returns an error -
'objectValues is not defined'.
I tried the underscore namespace, '_.objectValues...' with no success.
Any ideas?
Thanks,
Duke
