Mapping the map datatype on grails with SQL Server

Question

I have a domain class called Regra which has the following code:

Map<String, Permissao> permissoes = [:]
static hasMany = [permissoes: Permissao]

This was working fine while I was using the default in-memory grails database (jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE).

But when I started using SQL Server, some errors started appearing on the console log.

When I try to add an entry to the Regra domain class for the first time, I get the following stacktrace:

java.util.LinkedHashMap cannot be cast to java.lang.Number. Stacktrace follows:
Message: java.util.LinkedHashMap cannot be cast to java.lang.Number

If I make any change to the Regra domain class (even things like adding a blank line), and wait until Grails reloads this class, then everything works fine.

And this is the stacktrace I get when I restart the server after the table Regra already has some data:

Answer 1

From what I can read from the stacktrace seems that the exception is thrown in an indexing action. It could be a mapping issue between the domain class and the search index.
