[jira] [Commented] (WICKET-1856) AbstractTree XHTML Strict validation

["Mikk Lauringson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-1856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010050#comment-13010050 ] 

Mikk Lauringson commented on WICKET-1856:
-----------------------------------------

This problem is still present in latest wicket version 1.4.16. Why is it still unresolved several years later, if a working fix is known?

> I have a rootless BaseTree and see it output
>  <table style="display:none" id="tree1f_0"></table><table class="wicket-tree-content" id="tree1f_1"><tr>...
> which according to http://validator.w3.org is invalid strict XHTML. Looking at the
> comment in the code, AbstractTree.onRender(),
> 			// is this root and tree is in rootless mode?
> 			if (this == rootItem && isRootLess() == true)
> 			{
> 				// yes, write empty div with id
> 				// this is necessary for createElement js to work correctly
> 				String tagName = ((ComponentTag)markupStream.get()).getName();
> 				getResponse().write(
> 					"<" + tagName + " style=\"display:none\" id=\"" + getMarkupId() + "\"></" +
> 						tagName + ">");
> 				markupStream.skipComponent();
> 			}
> it appears from the comment that the indention was to output a div and not a table. With
> a div, we would get valid markup:
>  <div style="display:none" id="tree1f_0"></div><table class="wicket-tree-content" id="tree1f_1"><tr>...
> Is there a particular reason to fetch the tagName from the markupStream instead of just hardcoding
> it to "div"?
> Thanks,
> Kaspar
