Problem with custom profiles

Hi, I've got a weird problem...

I've added two custom profile fields. When I specify the values through the web user interface, I have no problems. However, when I specify them through the UserManagementWebService, and then try to view the users in Checkbox, I get an error

An application error occurred.

Error Message: Unable to cast object of type 'System.Int32' to type 'System.String'.

In the tables, the values *seem* to be set correctly;

ckbx_CustomUserField

CustomUserFieldID	CustomUserFieldName	Position	IsDeletable	Hidden
2	ContactID	2	0	0
3	EducationNumber	3	1	0
1	Email	1	0	0

jamesb	1	jamesb@education.co.uk
tapmantwo@hotmail.com	2	C99
tapmantwo@hotmail.com	3	123
jamesb	3	123
jamesb	2	C99

richard.tappenden@btopenworld.com	1	richard.tappenden@btopenworld.com
test	2	c1
test	3	012
test	1	a@b.c

Users jamesb & test shows fine - the others do not (both were entered manually into checkbox).

I can't see any other differences?

For reference, my code to create the user is as follows;

			Dim profileProps(2) As Checkbox.SimpleNameValueOfObjectObject
			profileProps(0) = New Checkbox.SimpleNameValueOfObjectObject
			profileProps(0).Name = "ContactID"
			profileProps(0).Value = registration.ContactID
			profileProps(1) = New Checkbox.SimpleNameValueOfObjectObject
			profileProps(1).Name = "EducationNumber"
			profileProps(1).Value = registration.EducationNumber
			profileProps(2) = New Checkbox.SimpleNameValueOfObjectObject
			profileProps(2).Name = "Email"
			profileProps(2).Value = registration.EmailAddress

			Dim addedToCheckBox As Boolean = False
			Try
				Dim checkboxResult As String = checkBoxWS.CreateUser(authToken.Value, registration.UserName, registration.Password, profileProps, True)
				addedToCheckBox = True
			Catch ex As Exception
				addedToCheckBox = False
			End Try

In my developer version, it all works fine!?

I'd appreciate any help I can get please.

I'm looking at the source for the edit user page right now. There is only one place where a value is cast to a string, though I can't see how the profile property value would have anything other than a string value, especially since the values are stored as nvarchar in the database.

Just out of curiosity, if you reset IIS then access the user manager, does the problem still exist for the users?

Thank you.

Hi,

I've just tested - and yes, if I restart the IIS service it fixes the problem. This obviously isn't a practical solution for me - the webserver runs many other web sites as well.

It's almost definately application caching or something - if I leave it a while (and the application stops/starts due to the .NET lifecycle) it starts to work.

Incidently - shouldn't it always be possible to cast an integer to a string (unless its null)?

Cheers

Richard

One workaround for the IIS reset is to put Checkbox in it's own application pool and recycle that. That's obviously not a long term solution, but may work in the interim until we are able to address the issue.
