Hi,
Thank you for your reply.
Actually I'm not reading data from database. I just giving input in the text
box and when I press Save button, the corresponding text field data is being
saved in the database.
But since wicket retains the page state using model, the textbox is being
filled with the rounded value I entered previously. Suppose I've entered 1.
and then pressed Save button, it shows 2 in the textbox.
Thank you.

Re: [Wicket-user] Problem handling Double values
Ok investigated it.And it is the way the NumberFormat.getInstance(locale); works (i tested it for the locale en )You get there a number formatter that does a RoundUp by default i guessthat number formatter will format 2 digits so
1.99but if you supply it 3 digits so 1.999 it will try to round up. When that happens you get 2.00If you don't want that you have to supply your own converterd for that so you have to override getConverter() of component
for you double fields. Or supply you own converter for everything through the converter factory.In 1.2 this is a bit harder to override/supply your own converters just for a specific type (both ways String<->Number)
in 2.0 this is much better and maybe we will try to backport it to 1.3johanOn 7/29/06, Johan Compagner <

[Wicket-user] Problem handling Double values
Hi,
I'm having
great problem with handling Double values in the text box. When I am entering a
double value in a text box with more than 3 precisions like 1.99 or 1.,
it is being saved in the database accurately,
but the post back value showing in the text box is rounded to next
Integer (in case of 1.99 or 1. it is showing 2).
My sample code is given below:
add(new
RequiredTextField("amount", Double.class));
Looking forward to have a good solution from you.
