I have a problem using HtmlDataTable for viewing data from database.
When I create <h:dataTable> component, the table has sometimes (not always) twice number of columns.
It is shown correctly and after several refreshes (without move in dtb or something) there is for example 6 columns instead of 3 and application (sometimes) become unstable.
Since this time I can't work with table because it reports "duplicate Id for a component"..
I have two working similar modules, and the third doesn´t work
Have you ever met this kind of problem?
