Hi Jeff.  Scrap that.  My dissector break point was after an if statement that fails.  I think I have a logic problem in the transum dissector.  I’ll work on it.

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

Are you saying your dissector isn't called again for any other frames?

 

·        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

So this means that if you click on, say, frame 2 (so you can see the packet detail area) the column is still not filled in?  Does your dissector get called when you click on the frame (it should be called--with 'tree' set).
