I want to re-configure the structure of the column header without rebuilding a new layer stack. Doing this I try to reconfigure the ColumnGroupHeaderLayer with following commands:

columnGroupHeaderLayer.clearConfiguration();
columnGroupHeaderLayer.clearAllGroups();
columnGroupHeaderLayer.addColumnsIndexesToGroup("Group 1", 1);

Is this approach an intended solution or is there maybe another recommended way to archive this?

Example to reproduce DynamicColumnHeaderHeightExample, with following changed lines in the button listener:

 button.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {
                filterRowHeaderLayer.setFilterRowVisible(!filterRowHeaderLayer.isFilterRowVisible());

                columnGroupHeaderLayer.clearConfiguration();
                columnGroupHeaderLayer.clearAllGroups();
                if (DynamicColumnHeaderHeightExample.this.toggleGroup) {
                    columnGroupHeaderLayer.addColumnsIndexesToGroup("Group 1", 1);
                } else {
                    columnGroupHeaderLayer.addColumnsIndexesToGroup("Group 1", 1, 2);
                }
                DynamicColumnHeaderHeightExample.this.toggleGroup = !DynamicColumnHeaderHeightExample.this.toggleGroup;
            }
        });

If you only want to change the column group structure, I don't think you need to call columnGroupHeaderLayer.clearConfiguration();

Actually I think this will create issues on the way because the necessary click and rendering configurations are removed. You should only need to clearAllGroups() and then configure the new column groups for this scenario.
