Dissector bug info: field casn1xxxprotocol is not of type FT_NONE

edit

So what does your code do for that field, please show us the proto_add_xxx function and the hf declaration.

Hi Grahamb,

I refactored old dissector code, in place of proto_tree_add_text(frame_tree, tvb, 0, 0, "NO Length field") i used proto_tree_add_none_format()

/* data structure to dissects all the bits of itsapp protocol */
static hf_register_info hf[] = {

        { &hf_xx_length,
            { "xxx Frame Length","xxx.flength",
                        FT_UINT16, BASE_DEC,
                        NULL, 0x0,
            "", HFILL }
                },
        { &hf_xxx_code,
            { "xxx Frame Code?","itsapp.code",
                        FT_UINT8, BASE_HEX,
                        NULL, 0x0,
            "", HFILL }
                },

    };
static hf_register_info hf[] = {
            { &hf_hdr_src,
                { "source","xxx.source", FT_STRING, BASE_NONE, NULL, 0x0,
                "", HFILL }},

            { &hf_hdr_dst,
                { "destination","xxx.destination", FT_STRING, BASE_NONE, NULL, 0x0,
                "", HFILL }},

            { &hf_hdr_protocol,
                { "protocol","xxx.protocol", FT_UINT16, BASE_DEC, NULL, 0x0,
                "", HFILL }},

            { &hf_hdr_msg_number,
                { "messageNumber","xxx.messageNumber", FT_UINT32, BASE_DEC, NULL, 0x0,
                "", HFILL }},

            { &hf_hdr_seg_number,
                { "segmentNumber","xxx.segmentNumber", FT_UINT16, BASE_DEC, NULL, 0x0,
                "", HFILL }},

            { &hf_hdr_num_segments,
                { "numberOfSegments","xxx.numberOfSegments", FT_UINT16, BASE_DEC, NULL, 0x0,
                "", HFILL }},
            { &hf_hdr_payload,
                { "payload", "xxx.payload", FT_UINT8, BASE_DEC, NULL,0x0,
                NULL, HFILL }},
        };

grahamb, i hope you remember about last conversation, I was debugged the dissector loading issue and fixed it.issue due to external dll dependency.

So what does your code do for that field, please show us the proto_add_xxx function and the hf declaration?

It will display sub protocol tree.

I Refactored old dissector code,in that they used proto_tree_add_text() which is obsoleted instead of that i replaced with proto_tree_add_none_format to display sub protocol tree.
