display a profile of the car on the same page - with h:selectOneListbox

Hi

My select list is like below .... and on selection of any of option on it i want to display a profile of the car on the same page .....what can be possible options and the best option ?

<h:selectOneListbox id="pickCar"
value="#{carBean.currentCar}">
<f:selectItems
value="#{carBean.carList}" />
</h:selectOneListbox>

Please tell me , how do i change the values of existing components on the screen on some valueChangeEvent ?

Thanks in advance

Several ways. Do you want to do it synchronously? Just submit the form to the server on change of the dropdown. Do you want to do it asynchronously? Consider using Ajax4jsf (part of RichFaces) to rerender the desired part of the page on change of the dropdown. Do you want to do it entirely clientside? Print all desired values to some Javascript array and use Javascript to display the desired part of the page on change of the dropdown.

The valueChangeEvent isn't of interest. You're not interested in the old value.

Thanks for reply

Ajax4jsf sounds best option here ....do you have any example ....

Thanks ...

Documentation, tutorials and examples enough at their own homepage.

Thanks

You need to do Ajax refresh after the onChange event of dropdown.

Below link is something similar.. but it uses IBM JSF Ajax component.
