[ https://issues.jboss.org/browse/DROOLS-1948?page=com.atlassian.jira.plugi... ] Michael Anstis commented on DROOLS-1948: ---------------------------------------- Hi [~jomarko] Nested grids are supported by using an ```ExpressionEditorColumn``` in a grid. This column's cell data-type is ```DMNExpressionCellValue``` that contains another ```GridWidget```. Rendering of the cell value is handled by ```ExpressionEditorColumnRenderer```. The cell value is populated from the DMN model by ```ContextUIModelMapper```.
