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()); }}); }

			if (event.item != null && event.item.getData() != null) {
				
				TreePath treePath = getTreePathFromItem((Item) event.item);
				selection = new TreeSelection(treePath);
				
			} else {
				selection = getSelection();
				updateSelection(selection);
			}
