ZK - Open Source Ajax Java Framework

Hi, im working on a project which uploads a lot of records through the excel, i should show the uploaded data with too many calculations to user, next the user submit the data to save in oracle (named deal), the problem is i have to clear memory just before detaching the window, but there is no event or some clear way to handle this kind of event (ondetach()), so program getting slower and slower, and tomcat hults after just 3 deals creation.

At the very first day i resist to use ZK, now this issue throwing me to hell, i would loose my job ASAP if i fail to solve this problem.
thank you

Hi ahoora,

I think you can not clear the memory used by the window before you detach it,
you may try clear memory just after detach the window:
1. detach the window and make sure no other reference of it
2. clear all data used by window
3. call system.gc()
