Thanks a lot for this worthful information I didn´t be aware of.
What I still don´t know how to add that field to our schema?
Do we have to change a certain file for this?
Sorry, I forgot that the script will update the schema for you. Just re-visit the page you created on your site with the !CreateXpdoClasses tag and it should update both the schema and the class and map files.
You can examine the schema file to make sure it has the new field. The schema file should be under the core/components/yourcomponent/ directory.
Thanks so much! Now it works for us!!!
I'm glad you got it sorted. Thanks for reporting back.
