UiBinder support for gxt.

How can i get right validation and autocompletion for gxt in UiBinder.

Now that code is incompatible to Idea validation (PercentageCalculator.ui.xml in attach):

<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'

             xmlns:gxt="urn:import:com.sencha.gxt.widget.core.client"

             xmlns:container="urn:import:com.sencha.gxt.widget.core.client.container"

             xmlns:form="urn:import:com.sencha.gxt.widget.core.client.form"

             xmlns:g='urn:import:com.google.gwt.user.client.ui'>

               <container:VerticalLayoutContainer>

                    ...

                    <container:child layoutData="{verticalLayoutData}">

                        <form:FieldLabel text="Sum">

                            <form:widget>

                                <form:NumberField ui:field="sum"/>

                            </form:widget>

                        </form:FieldLabel>

                    </container:child>

                    ...

              </container:VerticalLayoutContainer>

</ui:UiBinder>

there widget is child defined on subclass. I sopouse this bug relative (http://youtrack.jetbrains.com/issue/IDEA-93218).

and layoutData it's second parametr:

  @UiChild(tagname = "child")  publicvoid add(IsWidget child, VerticalLayoutData layoutData) {    ...  }

I've tried to define xsd for "urn:import:com.sencha.gxt.widget.core.client.container". Idea has linked it but ignor.

Mabe I missed something? Threre some special rules for UiBinder xsd?
