Hi Anthony

This is just a long shot from me - but have you referenced the upgraded dll's in your solution or are they still connected to the old ones? (If that makes sense?).

Hi Jan,

This could be the problem. I'll try it out and let you know if that solved the problem.

greetings,

Anthony

I removed and add new dll reference for:

umbraco.dll
cms.dll
interfaces.dll
businesslogic.dll

But I'm still getting the same error message.

The stack trace looks like this:

[ArgumentException: Could not find a IDataType control matching DataEditorId bf1a6031-dba9-4249-9baa-9124974eb09d in the controls collection. To correct this, check the data type definition in the developer section or ensure that the package/control is installed correctly.] umbraco.cms.businesslogic.datatype.controls.Factory.GetNewObject(Guid DataEditorId) +514 umbraco.cms.businesslogic.property.Property.MakeNew(PropertyType pt, Content c, Guid versionId) +723 umbraco.cms.businesslogic.Content.createNewVersion() +750 umbraco.cms.businesslogic.Content.CreateContent(ContentType ct) +260 umbraco.cms.businesslogic.member.Member.MakeNew(String Name, String LoginName, String Email, MemberType mbt, User u) +681 umbraco.cms.businesslogic.member.Member.MakeNew(String Name, String Email, MemberType mbt, User u) +36 UmbracoRegistration.Usercontrols.MemberRegister.MakeMember(MemberType mtype, String email, String password) in c:\repos\umbracoregistration\UmbracoRegistration\UmbracoRegistration\Usercontrols\MemberRegister.ascx.cs:188 UmbracoRegistration.Usercontrols.MemberRegister.btnRegister_Click(Object sender, EventArgs e) in c:\repos\umbracoregistration\UmbracoRegistration\UmbracoRegistration\Usercontrols\MemberRegister.ascx.cs:95 System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +155 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3804

I wonder if the the namespace: umbraco.NodeFactory; could have something to do with it, as I'm refering to this namespace in my code:

using umbraco.NodeFactory;

Thanks for your help,

Anthony

Hi,

Matt, thanks for the tip. I indeed installed uComponents. I'll install uComponents v5.

greetings,

Anthony

@Matt : you were right! I uninstalled uComponents and installed the latest version (v5.3) and now registration page is functioning again.

Thanks a lot man,

Anthony
