Background color not shown when cell label has no text in FlexTable

Hi!

This is a veeeery weird problem since it seems too bad to be true...
I have a FlexTable where all the cells are filled with Labels. Each cell has a CSS style since I want to update them individually when running the program.

The weird thing is that when a label is empty, as in Label emptyLabel = new Label(""); the background css won't show!
Has anyone heard of this?? :S

The java code:
eventTable = new FlexTable();
Label emptyLabel = new Label("");
eventTable.setWidget(row, 3,emptyLabel);
emptyLabel.setStyleName(tableCss.update());


CSS:
.update {
  background-color: yellow;
}

Thanks in advance! :D
