Getting URL parameter values in page region or inside taskflow can be achieved in following ways:

• Through groovy expression

It can be specified in region binding parameter value

${facesContext.externalContext.requestParameterMap['<parameter-name>']}

• In Managed bean

String paramValue = 
                 (String) FacesContext.getCurrentInstance().getExternalContext()
                 .getRequestParameterMap().get("param-name");
