What a bloody good question: This has had me stumped all week! Why isn't _ available in the tree tag? Phil ----- Original Message ----- From: "Chris Withers" <chrisw@nipltd.com> To: <zope@zope.org> Sent: Friday, August 18, 2000 1:32 PM Subject: [Zope] <dtml-tree, the bane of my life :(
Okay, firstly, I notice dtml-tree doesn't support the standard abbreviation:
<dtml-TAG "x"> -> <dtml-TAG expr="x">
As the following:
<dtml-tree "_.getitem('sequence-item',0)" branches="postingValues">
gives me:
Error Type: KeyError Error Value: "_.getitem('sequence-item',0)"
nice...
Now the one that has me stumped :(
Why does the following:
<dtml-tree expr="_.getitem('sequence-item',0)" branches="postingValues">
Give me: Error Type: NameError Error Value: _
This is all in 2.1.6...
cheers,
Chris
