Make a form with entities that have a specific attribute value

Is it possible to make a data grid which contains only the entities with a specific attribute value. For example I have customers with a enumeration(positive/negative). In the data grid I want to show only the customers which contains a specific value (positive) on that enumeration.

Yes, you can do that by setting a xpath constraint on your datagrid. You can find this one in the properties of your datagrid. Your xpath looks like:

[attributename = enumerationvalue]
