Warnings

I'm getting some messages like this one:

17:49:23.072:TMR8:WARN:TextItem:isc_TextItem_2033[dateTextField]:Attempting to apply event handlers to this item. Unable to get a pointer to this item's focus element

What could this mean?
using smartgwt 4.1p power 27.01

This basically means that our framework logic is failing to find the form item's handle -- or more accurately the "focusable element" in the DOM after the item has been drawn.

Can you show us how you're getting this?

An example:

@Override
	public void onModuleLoad() {

		VLayout layout = new VLayout();

		IButton clickMe = new IButton("click me");

		clickMe.addClickHandler(new ClickHandler() {

			@Override
			public void onClick(ClickEvent event) {
				MyWindow w = new MyWindow();
				w.show();
			}
		});

		layout.addMembers(clickMe);
		layout.setWidth100();
		layout.setHeight100();

		layout.draw();
	}

	private class MyWindow extends Window {
		public MyWindow() {
			setWidth(300);
			setHeight(300);
			LinkItem urlItem = new LinkItem("myUrl");
			urlItem.setLinkTitle("www.google.de");
			urlItem.setShowTitle(false);
			urlItem.addClickHandler(new com.smartgwt.client.widgets.form.fields.events.ClickHandler() {

				@Override
				public void onClick(
						com.smartgwt.client.widgets.form.fields.events.ClickEvent event) {
					com.google.gwt.user.client.Window.open(
							"http://www.google.de", "_blank", "");
				}
			});

			LinkItem linkItem = new LinkItem("myEmail");
			linkItem.setLinkTitle("info@info.com");
			linkItem.setShowTitle(false);
			linkItem.addClickHandler(new com.smartgwt.client.widgets.form.fields.events.ClickHandler() {

				@Override
				public void onClick(
						com.smartgwt.client.widgets.form.fields.events.ClickEvent event) {
					com.google.gwt.user.client.Window.open(
							"mailto:info@info.com", "_self", "");
				}
			});

			VLayout layout = new VLayout();
			DynamicForm df = new DynamicForm();
			df.setNumCols(1);
			df.setFields(urlItem, linkItem);
			layout.addMember(df);
			addItem(layout);
		}
	}

Thanks for the clear test case. We've found and fixed the issue.
Please try the next nightly build dated Feb 10 or above

I am also getting this issue and having searched the forum found this thread.

I have just upgraded my smartGWT pro version today (SmartClient Version: v10.0p_2015-02-18/Pro Deployment (built 2015-02-18)) and I'm still getting the warnings.

Sometimes the warnings appear and everything from a user perspective seems ok, most of the time however the link is disabled.

Seems like a timing issue as sometimes it will render correctly, tried attaching the click event in a schedule deferred event but that has made no difference.
