Hi,
I have run into a problem with datatables in my application. Values entered in some of my input fields in a datatable is disappering when the page is submitted.
The application is using Suns RI together with tomahawk, and is running on JBoss.
My application consists of a backingBean (TestBean), a jsp-page and a value object.
The jsp-page has a datatable with three inputfields, and a submit button.
This is my problem:
If I enter values in all of my three input fields, and hit the submit button, only the value in the first of my three inputfields is redisplayed after the submit. The values in the other input fields disappears.
This seems like a bug to me, has anyone else experienced this behaviour? Is there a known workaround or solution to this problem?
If I use sun's datatable all of the values are redisplayed as I expect them to.
The code is pasted below.
Regards,
Mette
