The issue re-appeared recently (in b114 or b115 I guess).

Please file a new issue. A bug that is marked as "Fixed" as the result of a changeset pushed to the repo should not be reopened for a partial or complete fix failure (unless that changeset was backed out).

Attached a NB project (same code) to reproduce more easily. See ScrollBarIssue.zip

Yes, the testcase, unit tests, and all the usual tests work. I didn't test with SB. The jira doesn't give exact details to reproduce in SB, so I though I'd check with the experts :-)

Sure, I'll test this in SB. I guess you checked with the test case ?

@Jerome : I've pushed a fix which should be in the next promoted build. If you can spare an cycles it'd great if you could check it out?

Mick, any news on this one ? This is very visible in SB.

I have filed RT-32448 to track this.

Mick, you can try to remove the big if(c.getContentBias() != ... ) blocks from canChangeVerticalSBVisibility and canChangeHorizontalSBVisibility. It should work although I won't be as effective. If we want to support children modification in compute* methods, I need to fix this in layout code to avoid such infinite loops.

I had to back out the proposed patch from Martin as it led to RT-32443. Therefore, I'm reopening this issue and reassigning to Mick to review.
20-08-2013
Applied Martin's patch.
30-07-2013
Assigning to Mick to review the patch from Martin and push to the repo if appropriate.
25-07-2013
Patch attached, returning back to controls for review. Since we don't have multiple layout passes anymore, the invalidation of ScrollPane layout when one of the scrollbars might change visibility must be done differently.
25-07-2013
This is almost certainly related to the scenegraph requestLayout() changes Martin has been working on, so I'll send it his way to triage appropriately.
