Error with userIndicator after extend User entity (cuba 6.10.7)

Support
#1

Hello!

I’ve extended User entity with new fields. All ok, except when I try to change to substituded user there is Exception:

IllegalStateException: Cannot get unfetched attribute [name] from detached object com.company.nl.entity.ExtUser-ea95eb71-2375-1caf-ead7-3c3fffd8bbbf [detached].

All other screens work ok
How to set right view to UserIndicator when user is changed?

Below full error log:

Solved problem by adding such view.

   <view class="com.haulmont.cuba.security.entity.UserSubstitution"
          extends="app"
          name="app">
        <property fetch="AUTO"
                  name="user"
                  view="_local"/>
        <property fetch="AUTO"
                  name="substitutedUser"
                  view="_local"/>
        <property name="startDate"/>
        <property name="endDate"/>
    </view>

This is correct or may be other solution?

Hi,

Would be great to see a test project where the problem is reproduced. Normally you shouldn’t extend the view for substitution to work.

Hello,

I have the same problem with CUBA 7.0.7 and this view solved the problem too.

Hi.
Unfortunately, we cannot reproduce the problem. Could you please share the extended User entity or a small project in order to help us investigate the problem?
