Issues in handling Keyboard events in a custom Grid

[SS]

Hi All,

I am facing tabing and keyboard events related issues in a custom
grid created using composite in our application.To handle all the
keyboard events we have a KeyDownHandler added to the focuspanel which
wraps the grid.Another listener is attached at the field level .This
field change listener sets the value to the context. When the user
types in fast or tabs out fast after making text entry , sometimes
field level listener is not invoked at all.KeyDownHandler , however,
is always invoked.This happens only if I type in fast .In the GWT
debug mode in the eclipse if I put a debug point in either
KeyDownHandler or the field change listener the issue is not
reproducible.

Any pointers to resolve this issue will be really helpful.

Thanks
