Migration from Yap rel. 1.x.x

The new event driven coding has changed the behaviour from the previous release.

If call Yap 1.x without any POST/GET parameter, it tries to establish if it is the first time the script run. If YAP finds its session data, it resumes the previous status. If it doesn't find anything, Yap assumes to be the first run.

Yap 2.x has changed his behaviour. If you run the script without any POST/GET parameter YAP, always, assumes to be the first run and remove all data (if any) from previous run. If you want resume the previous status you must use ev=YAP_DRAWCURRENT (i.e. http://mysite/myscript.php?ev=YAP_DRAWCURRENT).
