hello there,

thanks guys, now everything seems clear.


just another question

there are some records in DB that can be changed apart from SFS extension.
so how do I find about this?

I should call DB myself and see if a record is changed?

or there is build in function in SFS?

(sth like eventListener that listen for any change in DB in selected table)

you should probably redesign... else, you can send an event to the server via AS or java or any other language SFS supports i.e. a change was made to db via a php script, a reply is sent to the user about the change sucess, user sends an event to sfs extension, which then looks at a change that was made in the db... this is a bad design tho, you are better off just making changes to db via sfs, thus sfs will know what changes it has made (if you save them in a session or something)...

OR, you could use system calls, i.e. in php/c++ you could make something like:

//blabla some code to change db
//blbla check if success{
system('java someClientEmulatingExtension'); //run sfs extension to create an event
}

Making a cron-like script to see if there any changes is most inefficient...

guys, you were wrong!
