Hi Nicpan
Muramoto, what is in final the good package?
I’ll post here a snippet that does work, if you want to include it in the package.
Oh,Really?? Thanks! Please include it

I attach new file,beta5.zip.
I added new code that add an user to the default group, when exporting , calling OnWebSaveUser.
And some fix for ExternalIdMap.It’s sometimes cause to trouble.
I have had some tests for ExternalIdMap , export default group(clear my ExternalIdMap and Exporting, importing,etc) .
Maybe It’s OK!
I hope that the future version will have completely sync users and groups.
I want to manage users and groups on MODx perfectly.
To make this function, I need a lot of time.
<From 1.1beta4 to 1.1beta5>
1.Add new code that add an user to the default group ,when export new user,and call OnWebSaveUser event.
2.ExternalIdMap sometimes cause to trouble.So I modified and added check ExternalIdMap has connection between ExternalId and EntityId,or not.And If not,add ExternalId and EntityId to ExternalIdMap.
(I modified and added the code to import.class,export.class,plugin,snipet.)
<From 1.1beta3 to 1.1beta4>
1.Back to old code(g2cms.admin)
