107460 - Precondition: negative row in outliner GetCellAt() calc

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[Randell Jesup [:jesup] (needinfo me)]

When I try to turn off the "Total" column in mailnews, I get a "bad row"
assertion because aRow is -3.  This is due to:

#5  0x29c4953f in nsOutlinerBodyFrame::GetCellAt (this=0x9181214, aX=69, 
    aY=31, aRow=0xbfbf7fa0, aColID=0xbfbf7fb0, aChildElt=0xbfbf7fc0)
    at nsOutlinerBodyFrame.cpp:837

which calls AdjustEventCoordsToBoxCoordSpace ( aX, aY, &x, &y );, and this is
what we get for y:

(gdb) p *aRow
$3 = -3
(gdb) p y
$4 = -868
(gdb) p mRowHeight
$5 = 252
(gdb) p mInnerBox
$9 = {
  x = 0, 
  y = 0, 
  width = 2058, 
  height = 1470
}

This is quite repeatable.

Hyatt wrote this; pink factored out AdjustEvent....().

I think, I've already seen this. I'll look at it closely.
