UiBinder as Cell widget

[Deepak Singh]

Hi All,

I have an UIBinder widget.

I created a custom cell by extending AbstractCell as follows

public class ActivityCell extends AbstractCell<EachActivity> {

@Override

public void render(com.google.gwt.cell.client.Cell.Context context,

EachActivity value, SafeHtmlBuilder sb) {

if (value == null) {

return;

}

sb.appendHtmlConstant(value.getElement().getInnerHTML());

}

}

where <EachActivity> is a uibinder widget.

There are buttons and anchors inside this uibinder.

When added to celltable as a column, this gets rendered perfectly. But the event does not get fired when clicking on the buttons and Anchors of UIBinder.

Is there any solution ?

Help appreciated.

Thanks 
Deepak Singh

UiBinder does not handle Cell widget events. You probably want to use the upcoming Uibinder for Cells functionality (a.k.a. UiRenderer). It will be part of 2.5, but it is available in trunk, for the time being.

No documentation yet, but there is a design document here:

I'm using UiRenderer for cells, but I'm getting this error at compile time. (I'm using the trunk)

The code is very simple:

EntityBaseCell.ui.xml:

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">

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

<ui:with field="username" type="java.lang.String" />

<div>

<ui:text from="{username}" />

</div>

</ui:UiBinder>

EntityBaseCell.java

public class EntityBaseCell extends AbstractCell<EntityBaseProxy> {

 interface Renderer extends UiRenderer {

   void render(SafeHtmlBuilder sb, String username);

  }

 

 private final Renderer renderer;

  public EntityBaseCell() {

   renderer = GWT.create(Renderer.class);

  }

 

@Override

public void render(com.google.gwt.cell.client.Cell.Context arg0,

EntityBaseProxy arg1, SafeHtmlBuilder sb) {

   renderer.render(sb, arg1.getName());

}

}

Any Idea?

Which revision are you using? There's no call to getBundleAttributeParser from ComputedAttributeInterpreter:

I updated my local copy, I compiled and it worked! 

It's weird because I had done, something must have been wrong.

Now 2.5rc1 is out. 

Any document / example how to render uibinder (created by 2.4) to be used as column in celltable. And of course it should handle event from uibinder also.

Thanks in advance

Deepak
