Question: I was trying to use following code with GWT 2.2.0:

```
//in my UiBinderFile
<ui:style field="myStyle" src="MyCssFile.css"/>
.
.
<g:Label ui:field="aboutMainHeader" styleName="{myStyle.decorFont}"></g:Label>

```

and also in MyCssFile.css in same directory as UiBInder xml,

```
//entire MyCssFile.css
@font-face {
    font-family: cool_font;
    src: url('cool_font.ttf');
}
.decorFont{
    font-family: cool_font; /* no .ttf */
}

```

When I try to compile this, I get some NPE in UiBinder parser, right afer call of method that does font face parsing. I don't know what is wrong. Has anyone tried face-fonts with GWT, and could you please post working example?

Thanks...

Answer: 
See <http://code.google.com/p/google-web-toolkit/issues/detail?id=5247>

You'd have to put your `@font-face` declaration in an external (not-`CssResource`) stylesheet (could be inlined in you HTML host page for instance)
Because of the limitation [Thomas has noted](https://stackoverflow.com/a/5396034/9686) I've developed a small project to define font resources into GWT clientbundle's. It's still a beta but hopes you like it.
