We have made a change to the 3.1 and 4.0 branches which is likely to resolve this issue.
Please try the next nightly build and let us know if the problem persists for you.

If you do continue to see it and would like us to investigate, please post a runnable test case so we can reproduce it on our end

Thanks
Isomorphic Software

Thanks Isomorphic.

The problem still exists. Here is a TestCase for reproducing the behaviour:

Code:

public void onModuleLoad() {
	RootPanel.get("loadingWrapper").getElement().removeFromParent();

	SectionStack stack = new SectionStack();
	stack.setVisibilityMode(VisibilityMode.MULTIPLE);
	stack.setOverflow(Overflow.VISIBLE);
	stack.setCanResizeSections(false);

	stack.addSection(createSection(new HLayout(), 500));

	stack.addSection(getTestTree());

	stack.addSection(createSection(new HLayout(), 500));

	HLayout layout = new HLayout();
	layout.setOverflow(Overflow.AUTO);
	layout.setWidth100();
	layout.setHeight100();
	layout.addMember(stack);
	layout.draw();
}

private SectionStackSection createSection(Canvas canvas, int height) {
	SectionStackSection section = new SectionStackSection();
	canvas.setHeight(height);
	section.setExpanded(true);
	section.addItem(canvas);
	return section;
}

private SectionStackSection getTestTree() {
	final ExtendedDynamicForm productSelectorForm = new ExtendedDynamicForm();
	TreeGrid grid = new TreeGrid();
	grid.setHeight(500);
	final Tree tree = new Tree();
	grid.setData(tree);
	grid.setHilites(new Hilite[]{
			new Hilite() {
				{
					setId("foo");
					setTextColor("#555555");
					setCssText("font-style: italic;");
				}
			}
	});
	ButtonItem buttonManualProduct = new ButtonItem("add");
	buttonManualProduct.addClickHandler(new com.smartgwt.client.widgets.form.fields.events.ClickHandler() {
		@Override
		public void onClick(ClickEvent clickEvent) {
			tree.add(new TreeNode(), tree.getRoot());
			tree.openAll();
		}
	});
	productSelectorForm.setFields(buttonManualProduct);

	SectionStackSection section = new SectionStackSection();
	section.addItem(productSelectorForm);
	section.addItem(grid);
	section.setExpanded(true);
	return section;
}

Scroll to the middle and push the button. Now the pane is scrolled to the top position.

If you remove the hilites of the grid, the scrollPosition doesn't change.

Thanks for the test case. We have made some new changes which should address this
Please try the next nightly build (Dated Nov 13 or greater)

Hi Isomorphic,

Is there a release date when this fix will be oficially released ?

We wont be allowed to use the nightly build version for the release of our application.

Thanks
Ravi.

**Isomorphic** · 19 Nov 2012, 08:36

We'd recommend using today's 3.1d build. It's what's being deployed as the 3.1 release this over the next two days.

**rbhuta** · 29 Nov 2012, 22:22

Hi Isomorphic ,

Is there a patch fix for this we can apply to 3.0 to fix this issue.

We dont have the time now to upgrade to 3.1 and delay our release.

Thanks,
Ravi.

**Isomorphic** · 30 Nov 2012, 09:09

Sorry, this isn't something that can reasonably be applied as a "patch" to an older version.

You should either update to 3.1 or attempt an app-level workaround, such as a manual call to scrollTo() delayed via DeferredCommand / Scheduler.

**rbhuta** · 2 Dec 2012, 21:09

Hi Isomorphic,

Thanks for your reply.

The approach of scroll to or deferred command dosent help. I am trying a app level work around.

Thanks,
Ravi.
