Имам проблем, разработвам jsf приложение с openlayers api, този пример http://openlayers.org/dev/examples/vector-features-with-text.html работи добре с html страница, но когато сменя на xhtml страница, текстът на етикета не се показва. Надявам се, че някой може да ми помогне. Благодаря за отделеното време и помощта. Ето моят код.
