>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket-extensions
>    Affects Versions: 1.4.9
>            Reporter: Liam Clarke-Hutchinson
>            Assignee: Igor Vaynberg
>            Priority: Minor
>             Fix For: 1.4.11, 1.5-M2

>         Attachments: select-bug_reproduction.zip, Select.patch

> To reproduce using attached quick start:
> 1. Leave text field empty
> 2. Select a value in dropdown
> 3. Click submit link
> 4. The text field's validation will fail and the page will refresh with a validation error message
> 5. The dropdown's selected value will always be the first in the option list, no matter what value was selected in step 2.
> As the dropdown is updating its model via the AJAX behaviour, the value selected in step 2 should be the one selected when the page is redisplayed.
> We can workaround this like so: 
>         final Select select = new Select("select", New Model<String>("")) {
>             @Override
>             protected void convertInput() {
>                 super.convertInput();
>                 clearInput();
>             }
>         };
> As this removes the rawInput from Select, Select.isSelected then evaluates the models to determine the selected option. I have attached a patch in universal diff format that fixes this behaviour, and have tested it under all render strategies. I haven't written a unit test for this as the bug ultimately relied on submitted values not being available in a request, and I wasn't able to determine how to emulate this in a unit testing environment. (Pointers more than welcome. :) )
