Re: [Wireshark-dev] New Block: Columns not Rendered in Packet List until rescan

[Paul Offord]

Hi Roland,

Did a pull of master this morning, rebuilt with blocktype-trb and it now works 
fine.  I have made some minor changes to my code but nothing that is likely to 
fix the problem.  I guess it was a transitory problem with master.

Best regards…Paul

I’ve added a profile for the new dissector that adds trb columns into the

get this:

If I then do anything to cause a rescan (in this case change to Default profile 
and then back to my customer profile), the columns are populated:

Any ideas what I have missed?

Thanks and regards…Paul

[Wireshark-dev] New Block: Columns not Rendered in Packet List until rescan

[Paul Offord]

I've written a new block dissector called blocktype-trb - see 
https://code.wireshark.org/review/#/c/26203/  It works OK but I have a strange 
problem.

I've added a profile for the new dissector that adds trb columns into the 
packet list.  With this profile active I load a pcapng file with trb blocks and 
get this:

[cid:image005.jpg@01D3B254.879DF770]

If I then do anything to cause a rescan (in this case change to Default profile 
and then back to my customer profile), the columns are populated:

[cid:image006.jpg@01D3B254.879DF770]

Any ideas what I have missed?

Thanks and regards...Paul
