Conditionally render ButtonCell

[r4nd7263]

I'd like to show ButtonCell only on certain rows in a grid.

I tried

final ButtonCell<MyModel> btn = new ButtonCell<MyModel>() {
            @Override
            public void render(com.google.gwt.cell.client.Cell.Context context, MyModel value, SafeHtmlBuilder sb) {
                boolean condMet = ...
                if (condMet) {
                    super.render(context, value, sb);
                }
            }
        };
colCfg.setCell(btn);

which works in some browsers, but not all. Firefox and IE8 randomly throw javascript error when I mouse over a button.

You need to also add code to ignore events fired. I think the method you want to override is called onBrowserEvent(...).
