Stefan Betermieux updated MYFACES-688:
--------------------------------------
Attachment: HtmlRendererUtils.java.patch
I have fixed the bug in HtmlRendererUtils in my local copy. Maybe someone can
include this in the svn tree?
> displayValueOnly property on HtmlSelectBooleanCheckbox throws
> ClassCastException during rendering, second approach
> ------------------------------------------------------------------------------------------------------------------
>
> Key: MYFACES-688
> URL: http://issues.apache.org/jira/browse/MYFACES-688
> Project: MyFaces
> Type: Bug
> Components: Tomahawk
> Versions: Nightly, 1.1.0
> Environment: tomcat 5.5.7, java 1.5, linux 2.6.13
> Reporter: Stefan Betermieux
> Assignee: Martin Marinschek
> Fix For: Nightly
> Attachments: HtmlRendererUtils.java.patch
>
> When I create a HtmlSelectBooleanCheckbox and set displayValueOnly to true,
> an exception is raised during the rendering phase. During encodeEnd()
> HtmlRendererUtils.renderDisplayValueOnlyForSelects() is called.
> The following snippet causes the problems:
>
> if (uiComponent instanceof UISelectMany) {
> isSelectOne = false;
> selectItemList = RendererUtils.getSelectItemList((UISelectMany)
> uiComponent);
> converter = findUISelectManyConverterFailsafe(facesContext, uiComponent);
> } else {
> isSelectOne = true;
> selectItemList = RendererUtils.getSelectItemList((UISelectOne) uiComponent);
> converter = findUIOutputConverterFailSafe(facesContext, uiComponent);
> }
> Since the HtmlSelectBooleanCheckbox is derived neither from UISelectMany nor
> from UISelectOne but from UISelectBoolean, the cast to UISelectOne fails.
