I have a DataModel which contains IRoomDomain objects. Every IRoomDomain object has an IOccupancy array.
I want to use a data table to display them. Since every IRoomDomain can have several IOccupancy, I want to have a rowspan over the IRoomDomain IDs:
Var is room
Room ID| Label field 1 | Label field 2 | ...
-------|----------------------------|----------------------------|------
//Room1| room.occupancies[0].field1 | room.occupancies[1].field2 | ...
room.ID| room.occupancies[1].field1 | room.occupancies[1].field1 | ...
| room.occupancies[2].field1 | room.occupancies[3].field1 | ...
--------|----------------------------|----------------------------|------
//Room2| room.occupancies[0].field1 | room.occupancies[1].field2 | ...
room.ID| room.occupancies[1].field1 | room.occupancies[1].field1 | ...
| room.occupancies[2].field1 | room.occupancies[3].field1 | ...
--------|----------------------------|----------------------------|------
I tried a nested data table (1 column room ID, 1 column occupancy data), but it displays the header for every room, not once above as I want it to.
In addition, this construct must be selectable for the Room ID.
Is there any way to realize this with JSF/PrimeFaces? The data model can be changed, but the relation not.
Thanks in advance.
