I think i maybe found another bug:
if
@Override
public void render(Context context, MyValue data, SafeHtmlBuilder
sb) {
sb.appendHtmlConstant("<button class=\"gwt-Button\" >test<button>");
}
Clicking to the button fires a "click" only on the button if using the
improved onBrowserEvent you give me in the former link.
But if using a table wrapper:
@Override
public void render(Context context, MyValue data, SafeHtmlBuilder
sb) {
sb.appendHtmlConstant("<table>");
sb.appendHtmlConstant("<tr>");
sb.appendHtmlConstant("<td>");
sb.appendHtmlConstant("<button class=\"gwt-Button\" >test<button>");
sb.appendHtmlConstant("</td>");
sb.appendHtmlConstant("</tr>");
sb.appendHtmlConstant("</table>");
}
Using chrome trace tool I can see that the "click" event is fired but
onBrowserEvent is no even called!
using wrapper tables is a must to layout cells while no uibinder is
supported.
