Could someone guide me in the right direction here?
Here is the code for a component that I have:
public class CompanyInfo extends BaseComponent {
private Users user = new Users();
private Company company = new Company();
private boolean dispayLogo = false;
/**
* @return Returns the company.
*/
public Company getCompany() {
Visit visit = (Visit) getPage().getVisit();
return (visit.getCurrentCompany());
}
/**
* @param company The company to set.
*/
public void setCompany(Company company) {
this.company = company;
}
/**
* @return Returns the user.
*/
public Users getUser() {
Visit visit = (Visit) getPage().getVisit();
Users u = visit.getUsers();
return u;
}
/**
* @param user The user to set.
*/
public void setUser(Users user) {
this.user = user;
}
...../
}
When I log in with two different browsers on different machines I get
the following exception:
Unable to resolve expression 'company.name' for
[EMAIL PROTECTED]/compInfo].
binding: ExpressionBinding[CompanyProfile/compInfo company.name]
location: context:/WEB-INF/CompanyInfo.html, line 12
ognl.OgnlException
source is null for getProperty(null, "name")
Users() and Company() are my persistant Hibernate Classes. What is the
best way to do this? Basically this component shows information about
the current company that the user belongs to. I have stored the Users()
in the Visit and want to pull up this information.
Thanks.
