in SubTabLayout:

            Canvas canvas = currentSubTab.getCanvas();
            if (canvas != null) {
                if (hasMember(canvas)) {
                    if (!canvas.isVisible()) {
                        canvas.show();
                    }
                } else {
                    if (!canvas.isCreated()) {
                        canvas.setOverflow(Overflow.SCROLL);
                    }
---->               addMember(canvas);
                }
                markForRedraw();
                this.currentlyDisplayed = currentSubTab;
            }


The code gets into here, where the canvas already exists, but has no members. So canvas != null, hasMembers(canvas) == false and !canvas.isCreated() is false (i.e. canvas IS created).

In the debugger, I see that canvas.isVisible() is false (which is to be expected, it isn't shown yet).

However, I never see onDraw() get called nor RefreshableView.refresh() (which MemberView has - MemberView is "canvas" above).

Question: why doesn't the code do a "canvas.show()" here like it does in the "hasMembers" if clause???

If I add 

      if (!canvas.isVisible()) {
          canvas.show();
      }

after the addMembers call from my previous comment, this bug goes away.
Comment 3 John Mazzitelli 2011-02-28 19:40:55 UTC 
commit ca82e3d

added that if-statement to ensure the canvas is visible.

Verified on build#1086 (Version: 4.0.0-SNAPSHOT Build Number: 7b2d9f6)

The members view displays the member resources when navigating and coming back from another subtabs.

Marking as verified.
