As explained in my previous post, a new verification has been added before compiling WAD windows to detect possible errors.
The problem has appeared with the “Identifier verification” which forces all the tables used in the tabs to be generated to have at least one column set as identifier. This is strictly mandatory just in case the table is a part of a foreign key, but as now modules expose all their tables as part of their public API, we decided to force all tables to have identifier. But as before it did compile, it is possible there were modules with tables without identifier.
To solve this problem, now the verification does not stop the compilation process in case errors are found, but it is highly recommendable to fix them in your modules as soon as you see them to prevent possible incompatibilities with other modules. In a future core release, this check by default will stop the process, in case it is not successful.
