I have a problem that in my application I am using adg with headerrenderers for each column. In headerrenderer I included dropdown menu which is having filter labels and checkboxes.
by default all checkboxes will be checked in initially. when all these labels are checked in initially, if click on any value of that column I am able to show corresponding popup . when i unchecked any filter label in dropdown menu and unchecked any filter label , then i click on any value of that column , I am getting error saying that TypeError: Error #1009: Cannot access a property or method of a null object reference.
anyone help me out, thanks in advance.
