Hi,

 

I’m debugging a problem with the transum dissector.  Repro steps are:

 

·        Right click on a TRANSUM RTE Data value such as APDU Rsp Time and choose Apply as Column

·        The column is added with the correct heading

·        If I look at the Column preferences I see the APDU Rsp Time column with a type of Custom and the correct field name of transum.art

·        I get a single callback through my dissector with PINFO_FD_VISITED(pinfo) == TRUE for frame 1 which is the frame I am displaying

·        None of my other callbacks are called

·        The APDU Rsp Time for frame 1 shows correctly in the column

·        No other APDU Rsp Time values appear in the packet list even though the tree is correctly constructed in the packet detail area

·        If I close the trace file and open it again all APDU Rsp Time values appear

 

If I use Apply as Column to a value from another dissector, such as TCP Segment Len, all values appear immediately.  Have I missed something in my code?

 

If you want to see the code it’s available here - https://code.wireshark.org/review/#/c/17750/

 

Thanks and regards…Paul
