url - Vaadin 7 - Multiple browser tabs support -


i'm doing project in vaadin 7.

i found vaadin 7 manages multiple tabs problem automatically. but, i'm still facing issue.

i use icepush in project real time updates. (say, add row in table).

when open url in browser first time; works fine. no issues.

the problem occurs when open url in tab or when refresh url in same tab.

the row gets updated table in tab opened or refreshed last time , row gets added table number of times refreshed/opened url in tabs.

case 1: if open url in 3 tabs; row added 3 times in table in tab opened last(3rd tab).

case 2: if refresh url in same tab 5 times; row added 5 times in table in tab.

is problem vaadin? or think have done mistake in code?

actually problem made static reference table component. removed static reference. table working fine. and, not multiple tabs problem.
