Hi I have this error, data from database is not showing..
Etc. I have UsersService that implements IUsersService
I have added that UsersService extens PostgreSqlService and that service is extending main AbstractPostgreSqlService from Maven...
For some time that was working, but now not. The same error is when fetching table data and inserting and selecting...
This is error:

Luka Cavic wrote on Fri, 05 August 2016 16:24Hi, how to solve it by not adding order below service?
Now, I have many services, but only one service extends MainPostgreService(where is db connection methods) and has order below class name
When you don't add the @Order annotation, your bean gets assigned the default order of 5000. This is fine, as long as only one bean of a specific type exists. If more than one exists, you have to assign distinct orders to them. Alternatively, you can replace the bean from which you extend by adding the @Replace annotation.
See this section of the Scout documentation:
http://eclipsescout.github.io/6.0/technical-guide.html#bean-retrieval
Regards,
Beat
