1739932 - TB mochitest, JavaScript error: chrome://messenger/content/folderPane.js, line 2885: TypeError: can't access property "invalidateRow", this._tree is null

Status: NEW

(Thunderbird :: Message Reader UI, defect)

Description

[ISHIKAWA, Chiaki]

Lots of errors regarding invalidateRow from TB's mochitest, browser_ext_messageDisplayScripts.js.

I think this is architecture-agnostic, but I observe it when I ran DEBUG version of TB during mochitest under linux64 PC.

We have an issue with tree-comm-central in that the particular test is
not executed there, probably due to a crashing test in the list of tests
skipping the execution of several tests following it, including this
particular test. :-(
See the discussion in
https://thunderbird.topicbox.com/groups/developers/Te037635298392265

I am a bit surprised to realize all the errors come from a single test.

The following is an excerpt from a command run:

egrep "(invalidateRow|TEST_START)" /FF-NEW/log1350-mochitest.txt

This is coming from a heavily modified TB with local patches, and I am trying to see if I can run the test by excluding the crashing test on try-comm-central to show
the log (with less # of patches than on the local PC).
