While playing with the profiles, I have run into a small error, and maybe it's just a little confusion about the key/values for the profile properties, but I get this error: {"The settings property 'zipcode' was not found."}.  Also, the fields I do update are not saved to the database, even though I'm calling save.

I have a class derived from profile provider

 
public class NPSProfile : ProfileBase
{
 
public static NPSProfile CurrentUser
{
 
get
{
 
return (NPSProfile)(ProfileBase.Create(Membership.GetUser().UserName));
}
}
 
public static NPSProfile GetUser(string userName)
{
 
return (NPSProfile)(ProfileBase.Create(userName));
}
 
public string Address
{
 
get
{
 
return ((string)(base["address"]));
}
 
set
{
 
base["address"] = value;
Save();
}
}
 
public string City
{
 
get
{
 
return ((string)(base["city"]));
}
 
set
{
 
base["city"] = value;
Save();
}
}
 
public string State
{
 
get
{
 
return ((string)(base["state"]));
}
 
set
{
 
base["state"] = value;
Save();
}
}
 
public string Zip
{
 
get
{
 
return ((string)(base["zipcode"]));
}
 
set
{
 
base["zipcode"] = value;
Save();
}
}
 
public string Phone
{
 
get
{
 
return ((string)(base["phone"]));
}
 
set
{
 
base["phone"] = value;
Save();
}
}
 
 
}

That class has the corresponding entry in the web.config

<
 
profile defaultProvider="UmbracoMemberProfileProvider" enabled="true" inherits="NPS10x10.Umbraco.Profile.NPSProfile, NPS10x10.Umbraco.Profile">
<
 
providers>
<
 
clear />
<
 
add name="UmbracoMemberProfileProvider" type="umbraco.providers.members.UmbracoProfileProvider, umbraco.providers" />
</
 
providers>
<
 
properties>
<
 
clear />
<!--
 
<add name="address" allowAnonymous ="false" provider="UmbracoMemberProfileProvider" type="System.String" />
<add name="city" allowAnonymous ="false" provider="UmbracoMemberProfileProvider" type="System.String" />
<add name="state" allowAnonymous ="false" provider="UmbracoMemberProfileProvider" type="System.String" />
<add name="zip_code" allowAnonymous ="false" provider="UmbracoMemberProfileProvider" type="System.String" />
<add name="phone" allowAnonymous ="false" provider="UmbracoMemberProfileProvider" type="System.String" />
 
-->
</
 
properties>
</
 
profile>

If I uncomment the add statements, asp.net complains that they already exist.  So I uncomment them.  Then when I need to update the property I do this:

Profile.
NPSProfile p = Profile.NPSProfile.GetUser(CreateUserWizard1.UserName);
 
if (p != null)
{
p.Phone = 
"707-555-1212";
}

When I inspect p, I find that Zip doesn't exist.  I have the properties in the dashboard for the name to be ZipCode and the underlying file name to be zipcode (pretty much matching the class definition).
