Session variables

Hi there, We developed a site creation application but we recognised that Mendix does not have the ability to hold Session Variables. In nutshell, when a user enters an email address it is verified through an email verification service to make sure it is valid. The service charges per verification so ideally, the email address should only be checked once. However, currently the email address is checked every time when the user leaves the email textbox and it takes up verifications. If Mendix had Session Variables, we would be able to store the email as verified and this will be checked before sending the email for verification. Could anyone suggest a solution to achieve this? Thanks & Regards, Janos

You should be able to model this, probably through NPE (non persistent entities) associated with the Session entity in the system module. But maybe there's a simpler way.

can you explain how you implemented your approach?
