When you first install Latitude Studio, all components that require a backing data source are bound to a data source called default.json.
The endeca-portal\data\endeca-data-sources directory contains the default.json file.
The endeca-portal\data\endeca-data-sources directory also contains a default-schema.json file. It points to the same server and port as the default version of default.json, but is set up to only display configuration records.
You should also update default-schema.json to point to the correct server and port.
To update the default.json and default-schema.json files:
After you have updated the default.json and default-schema.json files, you can log in to Latitude Studio and begin adding components to your application.
For details on viewing configuration settings for data sources, see the Latitude Studio User's Guide.
