  Hi,

I think two ways are available to handle this :

  1. make a redirection at the end of your DTML method, adding a parameter 
(for example, upload=1) saying that upload was OK. In your first form, you 
just have to check for this parameter and display a message accordingly 
(<dtml-if upload>...</dtml-if>).

  2. I generally handle forms actions with Python scripts. At the end of these 
scripts, I add a volatile attribute to my object (self._v_modified=1) and in 
my DTML forms, I check for this attribute : if it exists, I display a message 
and then delete it immediately...
