540212 - ASSERTION: row count did not change by the amount suggested, check caller: 'rowCount == mRowCount' with test_open_first_message_in_smart_inbox in test-deletion-from-virtual-folders.js

Status: RESOLVED FIXED

(Thunderbird :: Folder and Message Lists, defect)

This is an annoying assertion that seems to happen only with smart folders, and the reason is that smart folders can add folders to the row map during generateMap (<http://mxr.mozilla.org/comm-central/source/mail/base/content/folderPane.js#980>, which results in <http://mxr.mozilla.org/comm-central/source/mail/base/content/folderPane.js#1683>). This causes our oldCount and the real old count to be out of sync.

Not sure how to write an automated test for this, but to manually test, you could run folder-display/test-deletion-from-virtual-folders.js with a debug build and see whether an assertion happens at test_open_first_message_in_smart_inbox.
