I am sorry Jonathan, I think we have a misunderstanding. All this works with web2py. The problem is that characters "<" and ">" need to be escaped in html. Otherwise, it is not html. The html produced by web2py is well formed but in the template itself the html it is not well formed. Because of this, the templates are not using well formed html all the times and the html code analyzer of my IDE is given me errors.
