So do you mean do something like this?
public abstract class CompanyInfo extends BaseComponent {
private boolean dispayLogo = false;
private Company company;
private Users user;
/**
* @return Returns the company.
*/
public Company getCompany(){
return(((CompanyProfile) getPage()).getCompany());
}
/**
* @param company The company to set.
*/
public void setCompany(Company company) {
this.company = company;
}
/**
* @return Returns the user.
*/
public Users getUser(){
return(((CompanyProfile) getPage()).getUser());
}
/**
* @param user The user to set.
*/
public void setUser(Users user) {
this.user = user;
}
}
