Hello! I have successfully extended User and all of its screens. The only problem I’m having is the following: on the ext-user-edit screen (user-edit’s child) there’s a substTable table, which shows substituted users. I am trying to add a column to this table (say, substitutedUser.lastName), but the datasource this table is working with does not fetch this field, as I can see in debug mode. It only fetches id and name (and maybe some other) fields that the parent screen works with. Any suggestions on how I could fix this?
Btw, the error I get when the screen is being loaded is the following:
IllegalStateException: Cannot get unfetched attribute [lastName] from detached object com.company.usertestproject.entity.UserExtension-60885987-1b61-4247-94c7-dff348347f93 [detached].
a full stacktrace:

Try to redefine the following view in your project:
<view class="com.haulmont.cuba.security.entity.UserSubstitution"
name="user.edit"
extends="user.edit">
<property name="substitutedUser">
<property name="login"/>
<property name="name"/>
<property name="lastName"/>
</property>
</view>
As you can see, I’ve added the lastName property to it.
