Hi, It's possible using trinidad or any other myfaces jsf impl to create a dataTable with dynamic columnGrouping? I.E. when i click in a column header it expands/collapses, grouping/disgrouping columns. Like if i have 3 column header rows, 1st for year and then a 2nd header row with 12 columns for months and then a 3rd header row for weeks, when i click in a month column header row it collapses his week columns and sum the corresponding values in a unique column.
I think what i need is a reRender of the table associated with action listeners, but for this this column headerrows need to be specified at java beans. I know this may be possible with normal columns, without any grouping, at least in ICEFaces i saw that, but with columnGrouping i have no idea how to set the header structure throw action listeners. Any help/ideas are welcome :) Regards Nuno -- Ping is just a number timming is everything
