Getting the "Choose Option" on page reload

[vinay.karmarkar]

Hi,



I have 2 drop-downs and a search button my page. When the page is loaded
for the first time, the first option in both the drop-downs is "Choose
Option". Now if I select some value and click Search, the page is
rendered again and the Choose Option is gone forever. But I want it
back. How do I go this?



Thanks.



Regards,



Vinay Karmarkar

you can set the dropdown model object to a value which you will read it from
pageparams,
and you will set the pageparams  in onsubmit,

 on first page load you will not be able to retrieve from pageparams so in
this case set the modelobject to default
value.

This is a browser thing.  It's remembering what you've selected on the
current form.  If you find a way around it, let me know.  Our page has
a pair of drop-downs too and we use ajax to populate the second one
when you choose something from the first one.  If you hit refresh, it
hoses everything up, because no select event happens on the first one
(but the browser selects something from it automatically because it's
"remembering"), so the second one doesn't populate.

It is a consequence of disabling null values; you need to tell the dropdown to accept null values which is what "Choose Option" represents:

theDropdownComponent.setNullValid(true);

You will also want to override the display value property in the .properties file:

theDropdownComponent.null_valid=Not set

Thank you for the responses. theDropdownComponent.nullValid=Choose one
worked.
