Hi, Why is the getter called only once ? How do I change the list of selectItems - is my code posted below ok for this ?
The submit is correctly rendered in the HTML code, I do get a ValueChangeEvent in which I then proceed to update the gui components as described below. I'd quite like to use Ajax, but I think I get the basics to work first, right now I am happy with a submit. kind regards, Peter > If you use component-binding, you need to keep in mind that the > "getter" of your component is only called once, whereas the setter is > called on every request. > > If you need to dynamically change the list of selectItems - you need > to do that in the setter. > > regards, > > Martin > > On 10/10/06, Gerald Müllan <[EMAIL PROTECTED]> wrote: > > Hi, > > > > can you post your jsp-code here? > > > > Have you added the attribute onchange="this.form.submit();" to the > > select menu in jsp code?
