Hi Pascal, I'm afriad you have to code a FIFO (first in, first out) and a FIFO manager : Each time you have to load something, you add the URL of the serverside file and the destination node where you want your new objets to be put in, in the FIFO. Then you call the FIFO manager.
The FIFO manager should know at any time if there is a httrequest pending. If not : when it is called, he should launch a httprequest whith the first item to load, and assigning the callback which should add the loaded data to the destination node, remove the loaded URL from the FIFO and lauch the FIFO manager again. If the FIFO manager is called and the FIFO is empty, noting is done. If the FIFO manager is called while there is still a pending HttpRequest, nothing is done That way, you can ensure that all data are loaded one after the other and you can add new data to load at any time. You can have an example of this on the site http://www.eure.pref.gouv.fr/sig/ouvre.asp on the comboboxes and the charging of the maps.

I would like to run an action only when I am sure the preceeding action is accomplished. In the same idea, is there a way to do like Flash when it is first loaded : Displaying an image like "Loading*" while all the loading is fully processed* Thanks >>>>-------------------------------------------------------------<<<< Ce message a été traité contre les virus par quatre outils différents (Kaspersky, McAfee, Symantec et Huntsman).
