[Laszlo-dev] Dataset SRC attribute can not be set

[Henry Minsky]

Where do you actually call the doRequest() method on the dataset?  Do you
call it manually?

If  the dataset is set to make the  request automatically, e.g., (the
'request' attribute == true) then
the request might get made before the constraint updates.

Also, what runtime are you using?
