Hi Paul,

I’m not sure if you’ve found a solution for this yet or not, but in case you haven’t, one thing that comes to mind is to remove an “if (tree)” checks you might have, as columns may need to be populated whether the tree is NULL or not.

Subject: [Wireshark-dev] New pcap-ng block requires a rescan

 

Hi,

 

I’ve reached a milestone with the TRB support; all basic Wireshark functionality is complete.  There is a remaining problem.  On opening a file, the blocks are decoded (see the protocol tree in the following screenshot) but the values are not rendered in the Packet List columns.

 

 

If I force a rescan (typically by changing to another profile and then back to the original profile), the column values are rendered.

 

 

I don’t think this is a problem with the TRB dissector.  I have tried figuring out what might be causing this problem, but I must admit I am struggling to understand how the column values are rendered.

 

Can someone give me a steer?  What areas should I be looking at?  How should I debug this problem?

 

Any help would be much appreciated.

 

Best regards…Paul
