I'm having an issue with Examine not rebuilding the indexes when I programmatically create a Member. Here's my code for creating a Member:

User author = User.GetUser(0);
MemberType mt = MemberType.GetByAlias(Constants.MEMTYPE_APPLICATIONUSER);
Member m = Member.MakeNew(name, mt, author);
m.Password = pass;

HttpRequest post = HttpContext.Current.Request;
string profileData = post["profileData"];

if (!String.IsNullOrWhiteSpace(profileData)) {
    m.getProperty(Constants.PROP_PROFILEDATA).Value = profileData;
}

m.LoginName = login;

m.Save();

ExamineManager.Instance.IndexProviderCollection[Constants.EXAMINE_MEMBERSEARCHER].RebuildIndex();

I've tried this with and without calling the RebuildIndex method on the IndexProvider, but neither works. What happens is that the index is updated with the new member, but the profileData property is blank in the index, even though it does contain data. I am indexing profileData in the index set also.  Here's my index set:

<IndexSet SetName="PointClickMemberIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/PointClickMemberIndexSet/">
    <IndexAttributeFields>
      <add Name="id" EnableSorting="true" />
      <add Name="createDate" EnableSorting="true" />
      <add Name="nodeName" EnableSorting="true"/>
      <add Name="loginName" EnableSorting="true" />
    </IndexAttributeFields>
    
    <IndexUserFields>
      <add Name="serialNumber" EnableSorting="true" />
      <add Name="groupID" EnableSorting="true" />
      <add Name="externalID" />
      <add Name="profileData" />
    </IndexUserFields>
    
    <IncludeNodeTypes>
      <add Name="ApplicationUser"/>
    </IncludeNodeTypes>
    
    <ExcludeNodeTypes />
  </IndexSet>

Any idea of what's going on?
