Summary: [Qt] instance objects created for QObjects are
somtimes GC'd
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: WebKit Qt
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: smagnuson at netflix.com
I have an QObject (A) with a child object (B). B's only reference in the JS engine is through A (ie A.B). I've attached some JS properties (in fact function handlers) to B, and I'm finding that at some point B was getting GC'd. Upon investigation I found that I could create a global reference to B (ie var keep_b = A.B) and the problem would go away - however this is clearly error prone and probably not as intended. I've fixed qt_instance so that it will go about marking
