Yes, you're trying to fight the technology.
Just do this.
public class YourBean
{
public String getActionForLinkPage()
{
FacesContext facesContext = FacesContext.getCurrentInstance();
String action =
(String)facesContext.getApplication().createValueBinding("#{param.linkPage}").getValue(facesContext);
return action;
}
}
<h:commandLink action="#{YourBean.actionForLinkPage}" value="#{linkText}"/>
