Yes, it should be collision-free by default without any action on your part.

It looks like you have a workaround, but if you can show how this can happen with valid usage we'd want to correct it.

Code:

public class TestingModule implements EntryPoint {

	ListGrid lg = new ListGrid();

	public void onModuleLoad() {

		VLayout vlayout = new VLayout();

		DynamicForm df = new DynamicForm();
		MyFormItem mfi = new MyFormItem();
		mfi.setWidth(300);

		df.setFields(mfi);

		vlayout.addMember(df);
		vlayout.setWidth(500);
		vlayout.setHeight(500);
		vlayout.draw();
	}

	private class MyFormItem extends StaticTextItem {

		private MyDialog picker;

		MyFormItem() {

			PickerIcon clearPicker = new PickerIcon(PickerIcon.CLEAR,
					new FormItemClickHandler() {
						public void onFormItemClick(FormItemIconClickEvent event) {
							clearValue();
						}
					});

			PickerIcon searchPicker = new PickerIcon(PickerIcon.SEARCH,
					new FormItemClickHandler() {
						public void onFormItemClick(FormItemIconClickEvent event) {
							Rectangle iconRect = getIconPageRect(event
									.getIcon());

							if (picker == null) {
								picker = new MyDialog();
							}
							picker.reset();
							picker.show();
							picker.moveTo(iconRect.getLeft(), iconRect.getTop());
						}
					});

			setIcons(clearPicker, searchPicker);

		}

		@Override
		public MyDialog getPicker() {
			return picker;
		}

	}

	public class MyDialog extends Dialog {
		TreeGrid employeeTreeGrid;

		MyDialog() {
			setWidth(700);
			setHeight(470);
			setAutoCenter(true);
			setIsModal(true);
			setShowHeader(false);
			setShowEdges(false);
			setEdgeSize(10);
			setShowToolbar(false);

			addCloseClickHandler(new CloseClickHandler() {

				@Override
				public void onCloseClick(CloseClickEvent event) {
					hide();
				}
			});

			VLayout vlayout = new VLayout(10);

			employeeTreeGrid = new TreeGrid();
			employeeTreeGrid.setWidth(500);
			employeeTreeGrid.setHeight(400);
			employeeTreeGrid.setNodeIcon("icons/16/person.png");
			employeeTreeGrid.setFolderIcon("icons/16/person.png");
			employeeTreeGrid.setAutoFetchData(false);
			
			employeeTreeGrid.setShowOpenIcons(false);
			employeeTreeGrid.setShowDropIcons(false);

			employeeTreeGrid.setShowSelectedStyle(true);
			employeeTreeGrid.setShowPartialSelection(false);
			employeeTreeGrid.setCascadeSelection(false);
			employeeTreeGrid.setCanSort(false);
			employeeTreeGrid.setShowConnectors(true);
			employeeTreeGrid.setShowHeader(false);
			employeeTreeGrid.setLoadDataOnDemand(false);
			employeeTreeGrid.setSelectionType(SelectionStyle.SINGLE);
			employeeTreeGrid.setOverflow(Overflow.AUTO);
			
			employeeTreeGrid.setShowAllRecords(true);

			vlayout.addMember(employeeTreeGrid);
			employeeTreeGrid.setDataSource(EmployeeXmlDS.getInstance());
			employeeTreeGrid.fetchData(null, new DSCallback() {
				
				@Override
				public void execute(DSResponse dsResponse, Object data, DSRequest dsRequest) {
					employeeTreeGrid.getTree().openAll();
				}
			});

			HLayout buttonLayout = new HLayout(5);

			IButton okButton = new IButton("Fetch tree");
			okButton.addClickHandler(new ClickHandler() {

				@Override
				public void onClick(ClickEvent event) {
					employeeTreeGrid.setDataSource(EmployeeXmlDS.getInstance());
					employeeTreeGrid.fetchData(null, new DSCallback() {
						
						@Override
						public void execute(DSResponse dsResponse, Object data, DSRequest dsRequest) {
							employeeTreeGrid.getTree().openAll();
						}
					});
				}
			});

			buttonLayout.addMember(okButton);

			IButton closeButton = new IButton("Close");
			closeButton.addClickHandler(new ClickHandler() {

				@Override
				public void onClick(ClickEvent event) {
					hide();
				}
			});

			buttonLayout.addMember(closeButton);
			vlayout.addMember(buttonLayout);

			addItem(vlayout);
		}

		public void reset() {
			employeeTreeGrid.setData(new ListGridRecord[] {});
		}
	}

}

Just click in the magnifier, then two times on "fetch tree", then you will see this:

Were you able to reproduce the problem with my test case? I would prefer to remove the workaround for this issue.

Maybe this is related to another thread: http://forums.smartclient.com/showthread.php?t=30610 where automatic ids seem to be colliding too.

**Isomorphic** · 7 Oct 2014, 09:02

This should be resolved by the next nightly builds.
