I'm still having a problem with FieldSet in both Chrome and Firefox. Here's the code:
FieldSet fs = new FieldSet(); fs.setHeadingText("Test");
fs.add(new TextArea(), new MarginData(10));
com.sencha.gxt.widget.core.client.Window w = new com.sencha.gxt.widget.core.client.Window();
The text area should take up the entire fieldset size, but it takes up only two lines on top. Same thing happens when I add a button instead of a text area. It almost looks like it's adding a child and allowing the child to choose its own height instead of sizing the child to take up all the available space, like a SimpleContainer would do.
