I have a problem, I develop an jsf application with openlayers api, this example http://openlayers.org/dev/examples/vector-features-with-text.html work fine with html page, but when I change to xhtml page the label text doesn´t showing. I hope anyone can help me, Thanks for your time and help. Here is my code.

尝试使用反斜杠转义 $： label : "name: \${name}\n\nage: \${age}"
