Compare error when importing any table


Scenario is this:

I create a new table in AOT and add 1 string field.

Then export the table to xpo file.

And after that import the same xpo I just exported.

Now when i hit Compare button on import form I get two errors:

Table , field group AutoSummary: method modelGroupId does not exist

Table , field group AutoSummary: method itemGroupId does not exist

And this is the case with all tables. I get the same two errors.

I have already tried compiling the application, did not help.

What could be the reason for this?

Is it some inconsistency in model database?

How to fix it?

Thanks for any clue!
