Wireshark · Wireshark-bugs: [Wireshark-bugs] [Bug 8266] post-dissector fields not saved in pdml

[bugzilla-daemon@xxxxxxxxxxxxx]

Comment # 4 on bug 8266 from Jono

Hi, yes sorry.

The Lua code below is my post-dissector plugin, run from init.lua.

It adds nodes to the tree displayed in Wireshark as expected, but if I export
the result using:   File->Export packet dissections->As XML ("PDML") .. the
nodes don't appear in the XML.

Cheers,
Jono
