DataGrid without id attribute bug in Studio

Hi,

I noticed that when you create a DataGrid using your preferred IDE, there is not mandatory to setup an idattribute :

`
<dataGrid id="ordersDataGrid"
                  datasource="ordersDs"
                  width="100%">
            <columns>
                <column property="date"/>
                <column property="customer"/>
                <column property="amount"/>
                <column property="description"/>
            </columns>
   </dataGrid>

`
like shows https://demo.cuba-platform.com/sampler/#! >> DataGrid basic settings.

…but if you do not specify an id attribute, and you go back to studio and open the layout of that XML, it will fail with message :


[15:37:52.959] Validation error
java.lang.reflect.InvocationTargetException
