Re: ActionCells within a CompositeCell not receiving onBrowserEvent()

Here's the link to the example code, http://pastebin.com/GbCRiZzu

If anyone has a working example of how to get ActionCells to work within a CompositeCell posting it would be much appreciated.

Thanks

Are you following the exact sample? or are you using the CompositeCell in your own project?

Can you paste the code where you are associating your CompositeCell with a table or CellList

Thanks for the help Ashwin, but I checked the import, com.google.gwt.dom.client.Element, and its correct, however the ActionCells within the CompositeCell are still not receiving the onBrowserEvent()  .

Daniel,

Check your import statement for the Element class. Thus should be using the .dom.Element package and not .client

Most probably that would be the issue for onbrowserEvent not getting invoked

Thanks

The ActionCell's onBrowserEvent() methods are not called.  Is there something I need to override in the CompositeCell or ConsumedEvents to make this work?

Below my example code, based on the Sample http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTree  ....

// Construct a composite cell for actions

List<HasCell<Item, ?>> hasCells = new ArrayList<HasCell<Item, ?>>();

hasCells.add(new HasCell<Item, Item>() {

private ActionCell<Item> cell = new ActionCell<Item>(

SafeHtmlUtils

.fromTrustedString(Utils.makeImage(deleteIcon)),

new ActionCell.Delegate<Item>() {

@Override

public void execute(Item item) {

listener.onDeleteClicked(item);

}

});

public Cell<Item> getCell() {

return cell;

}

public FieldUpdater<Item, Item> getFieldUpdater() {

return null;

}

public Item getValue(Item item) {

return item;

}

});

hasCells.add(new HasCell<Item, Item>() {

private ActionCell<Item> cell = new ActionCell<Item>(

SafeHtmlUtils.fromTrustedString(Utils.makeImage(editIcon)),

new ActionCell.Delegate<Item>() {

@Override

public void execute(Item item) {

listener.onEditClicked(item);

}

});

public Cell<Item> getCell() {

return cell;

}

public FieldUpdater<Item, Item> getFieldUpdater() {

return null;

}

public Item getValue(Item item) {

return item;

}

});

CompositeCell<Item> actionsCell = new CompositeCell<Item>(

hasCells) {

@Override

public void render(Context context, Item value,

SafeHtmlBuilder sb) {

sb.appendHtmlConstant("<table><tbody><tr>");

super.render(context, value, sb);

sb.appendHtmlConstant("</tr></tbody></table>");

}

@Override

protected Element getContainerElement(Element parent) {

// Return the first TR element in the table.

return parent.getFirstChildElement().getFirstChildElement()

.getFirstChildElement();

}

@Override

protected <X> void render(Context context, Item value,

SafeHtmlBuilder sb, HasCell<Item, X> hasCell) {

Cell<X> cell = hasCell.getCell();

sb.appendHtmlConstant("<td>");

cell.render(context, hasCell.getValue(value), sb);

sb.appendHtmlConstant("</td>");

}

};

Thanks in advance
