Anchor.wrap with GQuery
Hi, I am using GQuery to return elements that I want to attach ClickHandlers to like this: GQuery h2s = $("#header > h2 > a"); Anchor lowestPriceAnchor = Anchor.wrap(h2s.get(0)); But I am getting an exception: java.lang.AssertionError: A widget that has an existing parent widget may not be added to the detach list at com.google.gwt.user.client.ui.RootPanel.detachOnWindowClose (RootPanel.java:136) at com.google.gwt.user.client.ui.Anchor.wrap(Anchor.java:59) Does anyone know what I am going wrong here?

The element you're trying to wrap is a child of an element that's the "root" element of a widget. A widget is supposed to control its subtree, so wrapping a widget's child element in another widget is prohibited, as the "parent" widget would be aware of it. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

My question is _why_ is this element already owned and what can be done about it. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

First find the offending element (either set a breakpoint in RootPanel::isElementChildOfWidget in DevMode, or look for a parent element with a __listener property using whichever tool your like in "prod mode" –Firebug, Web inspector, Developer Tools, etc.–), then try to understand why it could "be a widget" already; but without seeing your code it's impossible to help you further more... -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
