Status: RESOLVED INVALID

Description

[timeless]

3017       nsIFrame* kidNextInFlow = kidFrame->GetNextInFlow();
3084       if (NS_FRAME_IS_NOT_COMPLETE(aStatus)) {
3085         kidNextInFlow = kidFrame->GetNextInFlow();
3086         if (!kidNextInFlow) {
3110           rowGroups.InsertElementAt(childX + 1, kidNextInFlow);

wrong code arises from bug 302911

Comment 2

[Bernd]

probably the url changed now to http://mxr.mozilla.org/mozilla-central/source/layout/tables/nsTableFrame.cpp?mark=2909,2930#2906 however I fail to see what is wrong with the code. The indentation in  of line 3110 in comment 0 is wrong. If there is no nextinflow the code below the if will try to create a nextinflow.

if if fails the code at previously at line 3110 will no execute. So what is exactly the issue here?

2800         if (!kidNextInFlow) {
2801           // The child doesn't have a next-in-flow so create a continuing
2802           // frame. This hooks the child into the flow
2803           rv = presContext->PresShell()->FrameConstructor()->
2804             CreateContinuingFrame(presContext, kidFrame, this, &kidNextInFlow);

2807             break;
2808           }
2809 
2810           // Insert the continuing frame into the sibling list.
2811           mFrames.InsertFrame(nsnull, kidFrame, kidNextInFlow);
2812 
2813           // Fall through and update |rowGroups| with the new rowgroup, just as
2814           // it would have been if we had called OrderRowGroups again.
2815           // Note that rowGroups doesn't get used again after we PushChildren
2816           // below, anyway.
2817         }
2818 
2819         // Put the nextinflow so that it will get pushed
2820         rowGroups.InsertElementAt(childX + 1,
2821                            static_cast <nsTableRowGroupFrame*>(kidNextInFlow));
