try with
FT_UINT32 and BASE_HEX
instead of
FT_UINT8 and BASE_DEC

I've already tried this solution previously but it was not right.
My Mask is coded with 3 bytes (24 bits).

So, I would like to have a display e.g. : 1010 1101 1111 1000 1011 1110 =
Mask : .....
I tried to mask with { "FOO PDU Type","foo.type",FT_UINT8, BASE_DEC, NULL,
0xFFFFFF,"", HFILL } but only the first 8 bits are displayed : 1010 1101.

thanks for your support
