Not enough information to say. The OL example work so in that sense they 
are "right way" to do it.
  Are we talking getfeatureinfo control or a vector popup?
  Have you configured your proxy used by the proxyHost setting if it is 
not a vector example?

The best way to delve into webmapping problems is getting used to using 
Firebug or Chrome developer tools. In this case, you should be looking 
at the Net tab and seeing is happening when you click on a feature. ie. 
what call does it make to the server and what response does it get. Make 
sure console is free errors. Nothing sent for wms/wfs layer means  
control not configured properly. No response means proxy issue. If you 
get a valid response, then problem is with the callback that setups the 
popup. You can set breakpoints and trace into the code.
