Bug 103747 [Viewers] calling refresh on treeviewer in treeExpanded function, but it mess
I tried calling refresh on treeviewer in treeExpanded function. The result is it mess up the tree, there is only one children without a label. Code to reproduce: public void createPartControl(Composite parent) { viewer = new TreeViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL); drillDownAdapter = new DrillDownAdapter(viewer); viewer.setContentProvider(new ViewContentProvider()); viewer.setLabelProvider(new ViewLabelProvider()); viewer.setSorter(new NameSorter()); viewer.setInput(getViewSite()); viewer.addTreeListener(new ITreeViewerListener() { public void treeCollapsed(TreeExpansionEvent event) { } public void treeExpanded(TreeExpansionEvent event) { viewer.refresh(event.getElement()); }}); }

}
			int i = 0;
			while (numItemsToDispose > 0 && i < items.length) {
				Object data = items[i].getData();
				if (data == null || items.length - i <= numItemsToDispose || !children.containsKey(data)) {
					if (data != null) {
						disassociate(items[i]);
					}
					items[i].dispose();
					if (i + 1 < items.length) {
						
						
						
						System.arraycopy(items, i + 1, items, i, items.length - (i+1));
					}
					numItemsToDispose--;
				} else {
					i++;
				}
			}

			Item item = items[i];
