Re: Using @UiChild with Elements not widgets, is this even possible?

Ah sorry, hadn't looked carefully at your code: with @UiChild(tagname="div"), UiBinder expects a <my:div> ("my" being the same as the containing widget):

<my:customWidget>

  <my:div>

    <ui:HTMLPanel>

      foo

    </ui:HTMLPanel>

  </my:div>

</my:customWidget>

That doesn't change the problem though: apparently (looking at the code), only widgets are allowed. With the above XML, the "my:div" only exists to call the @UiChild method, passing the HTMLPanel as argument.

Looks like I was wrong and you can only use widgets (there's an explicit "isImportedElement" test that checks the element is within a namespace whose URI starts with "urn:import:")

BTW, isn't the error message rather "Expected child from a urn:import namespace, found <div>" ?

Hi all,

Although the doc does say "...add a child widget to..." in my searching it seems as if you can also use UiChild with DOM elements that extend com.google.gwt.dom.client.Element class. Thomas Broyer gives a brief description here. Since it's Thomas I'm thinking this should indeed work, however for the life of me I can't get it to. It always ends up in "found unexpected child element: <div>" when the child is a div element. 

From the comments and the doc it seems that this is the setup you're supposed to have:

@UiChild(tagname = DivElement.TAG)

public void addDiv(DivElement div) {  //note: I've even tried "adddiv" just to be sure

  //do something

}

and in uibinder:

<my:customWidget>

  <div>foo</div>

</my:customWidget>

Do I just have code tunnel vision or is this not possible? Thanks in advance.
