Bob Schellink closed CLK-744.
-----------------------------
Resolution: Invalid
All Field#setValue works with Strings, not Options. It is consistent throughout
the framework. It is also used for copying values to and from domain objects.
Passing in Option from DataProvider is a good thing as it communicates clearly
what goes into the optionList to ther devs.
> Select control's setValue is not usable due to insufficient wrapping

> Key: CLK-744
> URL: https://issues.apache.org/jira/browse/CLK-744
> Project: Click
> Issue Type: Bug
> Components: core
> Affects Versions: 2.3.0-M1, 2.2.0
> Reporter: Sander van Grieken
> Attachments: SelectTestPage.java
>
>
> When calling setValue on a Select instance, it bombs out while rendering,
> regardless whether a String or an Option is passed.
> Passing an Option instance causes it to be 'toString'-ed as an Object (i.e.
> 'org.apache.click.control.opt...@1c154a3') when retrieving the selected value
> again.
> Passing a String causes it to throw a java.lang.IllegalArgumentException:
> Select option class not instance of Option or OptionGroup: java.lang.String
> at org.apache.click.control.Select.render(Select.java:998)
> I have modified the render(HtmlStringBuffer buffer) method in Select.java to
> additionally check for String instances, and in that case wrap it into an
> Option, and that works fine.
> if (object instanceof String) {
> Option option = new Option(object);
> option.render(this, buffer);
> } else ...
> The setValue method should probably be overridden from Field to also support
> the Option case
