Hi Tino,
 
thanks again - it's great that you are such an active member of the Mailing List. I must admit, I haven't understood your answer completely [newbie]. Would you mind explaining a little more? I have already created a design and I don't want to make input and sql-drop down on the same page.. Is it still possible? I didn't understand if your answer's 2nd part was a solution for the javascript-window design.

This is the part I haven't understood completely. Could you try to "fill" it with DTML so that I get a deeper insight :-)? How would I do it with GET? What's the difference between GET and POST (I have read the docs, I simply don't understand the difference for Zope! And: what if you don't supply any method=GET or =POST statements in your forms as done in the Zope Tutorial?). And more importantly: was your answer above related to javascript-window solution or "all in one page"-solution? I would need a suggestion for the javascript-window one.
 
My original idea was something like:
 
a) on the main site with sql-dropdown the link ("Create new drop-down entry")... [just a
    mindmap, no working code!!]:
 
   there's a link to the popup which passes the current REQUEST:
   <a href="<dtml-var URL>?<dtml-var REQUEST>"> or whatever...
 
b) when clicking refresh in the javascript window:
    top.refresh "mainSite(REQUEST)"
 
Again, is such REQUEST passing possible? Or: do you have a better idea?
 
 
Thanks again,
Philipp
