Hi,

So I had a simple browser screen. And I modified a little bit the XML. But I deleted my modifies and I got this exception and I do not understand why I got this and what is the problem:

15:44:31.136 ERROR c.h.cuba.core.sys.ServiceInterceptor - Exception:

Can you help me to solve this problem?

Thanks

Hi,

This is a very interesting situation - an entity is changed right after loading in a browser screen. What did you do in the screen to get this?

Hi Konstantin,

I tried to put the Edit screen’s field and actions button into the Browser screen. I copied only the XML part, but in my application I got a runtime error (can’t find action windowCommit), so I deleted it.
In the few days I’ve upgraded the project from 6.6.1 to 6.7.2.
I tried to regenerate the screen many times to start in the beginning, but no success.
And as I see now my another screen is affected with this ‘changed instance’ problem, but I don’t remember what exactly I modified, If I did.

The XML part:

<fieldGroup id="fieldGroup"
              datasource="CustomersDs">
        <column width="250px">
            <field id="Name"/>
            <field id="BirthDate"/>
            <field id="..."/>
        </column>
    </fieldGroup>
    <frame id="windowActions"
   screen="editWindowActions"/>

Okay, so what I know now is that something is wrong with my datas in my database, because when I changed my database into an empty one, then it worked perfectly. But when I created new record there then the error is came back. So I think something wrong with my another code.
Thank you.
