pop-up ad blockers are often the culprit -- the main page is trying to find
info from the blocked page. If you're a JavaScript programmer and are
having trouble keeping passed values available once you have closed a
popup, read on...
For what it's worth, I needed to popup a window, submit a form to my
database, create an array from the result and return it to a global
variable of the window.opener. As long as the popup window was open the
opener window could reference the array. But I needed to close the window
because its only reason for being was the trip to the database. Nothing
displayed on it.
Even tougher -- the variable name needed to be based on input from the
user so I couldn't predefine it on the opening window.
As soon as the window was closed I got the same error:
Error: The callee (server [not server application]) is not available and
disappeared; all connections are invalid. The call did not execute.
After playing with passing back the array as an array in every way I could
think of, I gave up and decided to return a string with the array values
delimited. That meant having to parse the string into an array using
split() when the values were needed, but at least the kludge works.
