Use of Java synchronized at the server, on dispatchers execute methods?

[Fille]

I just realize when I press a button many times fast in the UI for fetching data from the server, I get redundant result. From race condition i guess.

Should i add "synchronized" on the execute method's on the server. Or should i use some client mechanism?

What do you think is the best solution?

I usually put the button in a disabled state while doing a request.

I guess to be on the safe side you should do both. 

Disable the button and synchronize on the backend.

Allright, thanks!

I'll stick with synchronized on the server and add the functionality with disabled buttons.
