Hi guys,
I am running a live project on DW10.22.15 (hosted in Dynamicweb cloud)
I am trying to export users from Backend using the standard Export functionality and the Default preset.

I get this error:
 

2026-04-22 11:34:40.1279: Error while saving command log for model. Model Type: 'Dynamicweb.Users.UI.Models.UserListModel', Model ID: ''.. System.ArgumentException: Invalid revision data. Original model or updated model do not have the same type: 'Dynamicweb.Users.UI.Models.UserListModel'.

Is this a bug or something to do with my instance?
Thank you,
Adrian

Also, when I try to export a custom field, I get this error:
An unhandled error occurred: Property CustomFields|AccessUser_DefaultLocation does not exist on Dynamicweb.Users.UI.Models.UserDataModel, Dynamicweb.Users.UI

I added a custom field on the interface using "Manage columns" then tried the export again.

I can reproduce you second issue. https://doc.dynamicweb.dev/documentation/fundamentals/dw10release/releasenotes/workiteminfo.html?workitemid=28026

I think your first issue might have been fixed in later versions - at least I can do an export on the latest. The above contains a fix for both.

We have just made some changes to export to excel from the backend in latest R0 - maybe R1 - that makes exporting large amounts of data better.
