Yes, commandLink and commandButton will render an anchor tag. If you don't want to do this you can do work in your properies getter method when it gets called by outputText value and return an empty string. However, I don't believe there is any guarante as to call order. Putting your target outputText in the first line of your jsp file doesn't mean it will get called before other getter methods further down in the jsp file get called.
