HtmlPanel, custom tag and binder

[David Ignjić]

Hello,

I have problem with widget:
Ui binder file:

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent";>
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui" 
xmlns:t="urn:import:com.umantis.talent.client.thirdappraisal.widget">
<g:HTMLPanel tag="tr">
<td><g:Label ui:field="label"></g:Label></td>
<td><g:Label ui:field="period"></g:Label></td>
<td><g:Label ui:field="description"></g:Label></td>
<td><t:ValueRadioList ui:field="givenAnswer"></t:ValueRadioList></td>
<td><g:DoubleBox ui:field="scoreValue"></g:DoubleBox></td>
<td><g:TextArea ui:field="givenComment"></g:TextArea></td>
</g:HTMLPanel>
</ui:UiBinder> 


Java file:
package com.umantis.talent.client.thirdappraisal;

import java.util.Map;
import com.google.gwt.core.client.GWT;
import com.google.gwt.editor.client.Editor;
import com.google.gwt.text.shared.AbstractRenderer;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.uibinder.client.UiField;
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.DoubleBox;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.TextArea;
import com.google.gwt.user.client.ui.Widget;
import com.umantis.talent.client.thirdappraisal.widget.ValueRadioList;
import 
com.umantis.talent.shared.dto.thirdpartyappraisal.ThirdPartyAppraisalQuestionEvaluationModel;


public class QuestionEvaluationEditor extends Composite implements 
Editor<ThirdPartyAppraisalQuestionEvaluationModel> {

    private static QuestionEvaluationEditorUiBinder uiBinder = 
GWT.create(QuestionEvaluationEditorUiBinder.class);

    interface QuestionEvaluationEditorUiBinder extends UiBinder<Widget, 
QuestionEvaluationEditor> {
    }

    @UiField
    Label label;

    @UiField
    Label period;

    @UiField
    Label description;

    @UiField(provided = true)
    ValueRadioList<Long> givenAnswer;

    @UiField
    DoubleBox scoreValue;

    @UiField
    TextArea givenComment;


    private Map<Long, String> dynamicListAnswers;

    public QuestionEvaluationEditor() {
        givenAnswer = new ValueRadioList<Long>(new AbstractRenderer<Long>() 
{

            @Override
            public String render(Long object) {
                return dynamicListAnswers.get(object);
            }
        });

        initWidget(uiBinder.createAndBindUi(this));
    }

    public void setDynamicListAnswers(Map<Long, String> dynamicListAnswers) 
{
        this.dynamicListAnswers = dynamicListAnswers;
        givenAnswer.setAcceptableValues(dynamicListAnswers.keySet());
    }
}


I get the error
java.lang.RuntimeException: Cannot find element with id "gwt-uid-67". 
Perhaps it is not attached to the document body.

But if I change line 
<g:HTMLPanel tag="tr"> to <g:HTMLPanel> all working as expected.

I looked into source and problem is with this line
    setElement(scratchDiv.getFirstChildElement());
-->this line    getElement().removeFromParent();


Ok How to solve this ?.


Thanks David Ignjic
