EasyVista Discussions Data Source
This data source belongs to the Applications category in the data source library. It is used to define a dynamic data source associated with 
discussions.
- Discussions are displayed using a Discussion widget.
- A filter enables you to display all discussions or only those that the logged-in user is authorized to see.
- A master-detail relationship between a Data Viewer widget and a Discussion widget linked to the data source will display only the discussions related to the current object.
See the example.
Notes
See General remarks on data sources.
- Discussions related to the current object are displayed by specifying the master-detail relationship, i.e. the relationship between the Data Viewer widget and the Discussion widget linked to the data source. See the procedure.
Example
You want to display all discussions on the current problem. See the procedure for the Discussion widget.
