Hi,
i use an extendedDataTable with 4 columns. the table is grouped by the first column programmatically (works fine with richfaces 3.3.0 :).
now the user has the possibility to hide the first column and to hide the subrows of the groups.
but is there any way to do this programmatically?
thus i want to present an extendedDataTable with 4 columns grouped by the first. furthermore the first column should be hided and the groups should be collapsed without any user interaction.
