i need to get a value from a GWT App. If i inspect the page/element with FireFox, i only find:
<input class="GM53QT1CF GM53QT1CF-readonly" type="text" style="height: 26px; width: 98px;" readonly="">

But there, or somewhere else in the HTML Tab of FireBug, is not the value i can see on the screen. A coworker told me to have a look in the DOM Tab of FireBug, there i can find the value.

value "0.518"

How can i capture this with selenium?
