What I am trying to do is set up a blank UL container I can fill from my
control code..
ie. below, where UnorderedList is a Java class that I used the source
from HTMLPanel
as a starting point..
<?xml version="1.0" encoding="UTF-8"?>
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
xmlns:MyWidget='urn:import:com.mypackage.ui'>
<g:HTMLPanel>
<MyWidget:UnorderedList ui:field="galleryContainer"/>
</g:HTMLPanel>
</ui:UiBinder>
The above works fine, and I can access the galleryContainer object as a UIField
in my control code..
but if I want to add some static list elements, mostly to see how they look in
GWTDesigner, it fails..
i.e.
<?xml version="1.0" encoding="UTF-8"?>
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
xmlns:MyWidget='urn:import:com.mypackage.ui'>
<g:HTMLPanel>
<MyWidget:UnorderedList ui:field="galleryContainer">
<li><img href="somepic.jpg"/></li>
</MyWidget:UnorderedList>
</g:HTMLPanel>
</ui:UiBinder>
When I go to open GWTDesigner, it fails initialization saying the element
MyWidget:UnorderedList
is only expecting Widgets. I pulled in the source for HTMLPanel into my
UnorderedList class in its
entirety and only modified it to produce UL elements instead of Div elements.
Not sure what's going on here, I get the feeling that there is some description
file somewhere
telling which UI elements are allowed to contain HTML vs Widgets somewhere
since the code is
the same as HTMLPanel.

There are two ways to add html tag inside the HTMLPanel. You can add
Unorder List / ListItem (UL/LI) directly to HTMLPanel, or using HTML
class inside the HTMLPanel. Try the below code.
//.xml file
<?xml version="1.0" encoding="UTF-8"?>
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:DockLayoutPanel unit='EM'>
<g:west size='10'>
<g:HTMLPanel>
<g:HTML>
<ul>
<li>ListItem</li>
<li>ListItem1</li>
<li>ListItem2</li>
</ul>
</g:HTML>
</g:HTMLPanel>
</g:west>
</g:DockLayoutPanel>
</ui:UiBinder>
//.java
public class HtmlTest extends Composite
{
interface Binder extends UiBinder<Widget, HtmlTest>{}
Binder binder = GWT.create(Binder.class);
public HtmlTest()
{
initWidget(binder.createAndBindUi(this));
}
}
