Has anybody upgraded an old custom field type to use the new XSL transform in SharePoint 2010? I have a multi-column field type, and want the Display pattern to render the 2nd "column", which contains a hyperlink. My CAML render pattern looks like:
<RenderPattern Name="DisplayPattern">
<Switch>
<Expr>
<Column />
</Expr>
<Case Value="" />
<Default>
<HTML><![CDATA[<a href=']]></HTML>
<Column SubColumnNumber="1" HTMLEncode="TRUE" />
<HTML><![CDATA['>]]></HTML>
<Column SubColumnNumber="1" HTMLEncode="TRUE" />
<HTML><![CDATA[</a>]]></HTML>
</Default>
</Switch>
</RenderPattern>
In WSS 3.0, this would render the 2nd column in the field as a hyperlink in the LVWP, which is what I want. In SharePoint 2010, I tried adding TRUE to my field type definition, but that ends up rendering the actual anchor tag, as opposed to a clickable hyperlink:
<a href="http://www.something.com">www.something.com</a>
So then I tried creating a XSL transform, since that is supposed to be the new and improved way of doing this. Unfortunately, I can't get that to work either. I am getting the same thing I got using the RenderPattern. I'm no XSL expert, so can anyone confirm (or deny) that the following looks legitimate (or suggest a better way to do it)?
