Can you show your page design? Maybe the dataview is somehow out of scope.
Hi Andreas Blaesius,
Iam adding the pics here that I did the design with DataGrid 1.
1.First Pic shows the list of task and subtask. Subtask is listening to the grid Task Using DataGrid 1
2.the below pic shows the list of task and subtask using DataGrid 2. BUt in this case subtask is not listening to Task.
This is currently a limitation of the Datagrid 2 (and other pluggable widgets). This is something we will plan to fix in the future.
