Thanks Chuck, Paul and Mike for your help
The principal problem was that Migrations functionality is called automatically
after my own code that loads some info from de data base, so if the migration
has changes in a table that is considered in my code the app crashes before the
migration occurs.
The solution is to add the Chuck's code before everything else in the
constructor of my Application class.
if (ERXMigrator.shouldMigrateAtStartup())
{
try
{
migrator().migrateToLatest();
}
catch (ERXMigrationFailedException e)
{
// It might be a missing plugin problem
new
ERXJDBCConnectionAnalyzer(databaseConnectionDictionary());
throw e;
}
}
