Hi,
Something strange happens to me for a flash message.
Have a form, and when this one is correctly filled and the user clic on ok,
a calculation is done.
Depending of the result on this, I have to stay on the form and put an
(error) flash message to the user.
In this last case, nothing happens on the first clic on ok (the use stays
on the same form, no message).
The message is displayed on the second clic...
Can someone please help me ? Thanks :)
