Using rich:dataTable and rich:columns together to display th
Hi,
I have a requirement where my columns in a table will be picked up from configuration (web.xml). So, displaying the table content using rich:column is ruled out. I tried using rich:columns and I am able to display the information. But, when it comes to sorting of columns, it is not working.
I have a runningJobs.xhtml file which displays information from RunningJobsBean (request scope). The columns are picked up from web.xml. I manually build column objects using Column class which also has the Ordering field set by default to the first column. But the requirement here is that I should be able to sort the column values on any column.
When I get the output on the tab, I am able to sort it once. But, after that, the sorting functionality does not work.
I am attaching the code. Please help!
Regards
Anand
