Hi Tomas,
First, pls. let me thank you and the team for the amazing work on GWT.
As for the documentation, I'd say it's lacking an example for importing
custom widgets because the way some of use read the XML. Personally I just
automatically skip over the xmls section because it contains "standard" GWT
namespaces.
I think the docs would benefit from explicitly stating
"To import your own widget com.example.gwt.client.SampeTextField, use the
xmlns to add a package with your own packages and then use the prefix in
the body of the template. For example:
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:e='urn:import:com.example.gwt.client'>
<e:SampeTextField displaySize=10/>
</ui:UiBinder>
"
