To quote README.developer, "No field type. Used for fields that aren't given a value, and that can only be tested for presence or absence..." - so there wouldn't be anything to be displayed in the custom column. What are the dynamic values you are displaying?No, i'm not sure. I want to show a piece of the packet-header in human readable,sortable format. i.e.: Value Column-Text 0 "[Ct]" 1 "[Ct]" 2 "[Nt]" 3 "[Nt]" 4 "[Qt]" 5 "[Escape]" 6 "[Mt]" 7 "[Mt]" Thats shouldn't be difficult, but the value 7 is dependant on the packet type either "[Mt]" or "[Pt]". So i can't use the normal proto_tree_add_item and value_string contruct. The background is, i want to clean some things in the DECT dissector (packet_dect.c). There are many things to do, one of them is that all infos from the packet only are written to COL_INFO since Revision 28022 (http://anonsvn.wireshark.org/viewvc/trunk/epan/dissectors/packet-dect.c?r1=27904&r2=28022). Now i want to write this infos to custom columns, not to any random chosen COL_xxx fields like before. The upper described example is the first thing that be showed in the COL_INFO column and depends on dect.AField.head.TA and dect.type (or COL_PROTOCOL == DECT RFP/DECT PP).
