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? You have to do a submit after changing the selection, otherwise you will only stay on the client. For this kind of usecase you can also use the ajax enabled combobox from sandbox, as it is shown on our examples page: http://example.irian.at/example-sandbox-20061010/ajaxChildComboBox.jsf Would be a more fluid flow for the user. cheers, Gerald On 10/10/06, Peter Rabing <[EMAIL PROTECTED]> wrote: > Hi, > > I've created a component with a binding expression in which I created a component tree. > The Tree contains 2 combo boxes with some items.
