I can't provide you with a url at this point and the code is up there :
a layer and it's associated textfile.

Then why form 1 works and form 2 doesn't ?  I use the exact same
textfile and in one case I get a title and features on my map if I do
not specify icon related attributes in my text file and in the other
case I get "Undefined" for a title and icon* attributes are not
optional.  Whence my question.

I'm using the Format.Text layer for a website that is deployed on Yahoo
(no spatial DB available on that machine, just MySQL).  I thought it was
pretty neat to use a textfile and get a popup, but of course I got
caught in trying to alter OpenLayers.Layer.Text's popup (no framedCloud
there) so now  comes a way to get a framedCloud popup with a textfile so
I try it.  The other thing is I could use an OGR virtual file to map a
MySQL table, but I'm not sure I can deploy OGR on Yahoo.  It's so much
simpler with a textfile.
