I think Spring may be trying to bind to the company property on your user
object. The way I would recommend you manage the relationship is to inject a
custom property editor in your controller using the initBinder() method from
the parent controller. That way you can get rid of the companyId property on
your user object, and you can let Spring do the binding for you.
To register a new binder do something like:
servletRequestDataBinder.registerCustomEditor(Company.class, "company", new
CompanyPropertyEditor());
where CompanyPropertyEditor looks something like:
class CompanyPropertyEditor extends PropertyEditorSupport
{
public void setAsText(String text) throws IllegalArgumentException
{
Company company = null;
if (StringUtils.isNotEmpty(text) && StringUtils.isNumeric(text))
{
company = companyManager.getCompany(new Integer(text));
}
else
{
text = null;
}
super.setValue(company);
}
public String getAsText()
{
Company company = (Company) super.getValue();
return company == null? null: company.getId();
}
}

Hi,
Yes I have a property called Company, I use 'companyId' to assign the
company in the UserFormController... actually hibernate is the one that
manages the relationship...here it is part of my pojo..
What can be the problem??
Thanx
