[Zope] Re: images in trees. Any solution??

[Gilles lavaux]

Hello,

I am moving stuff from zope1 to zope2 and had this problem to:
  Inside a tree tag displaying an image with <dtml-var image_name> failed
but with <dtml-var "image_name"> it works.

I would like to know what is the normal behavious of the tree tag,  shall I
change my code to add the "" arround the image name?? I display a lot of
small documents inside my tree , thoses document containing images
(dot,etc..) so it's a lot of modification to do.

Thanks for any info

Gilles Lavaux
