Error using abstract class uiBinder

[Luis Costa]

Hello,

I'm using GWT SDK 2.4.0 and I'm trying to create an abstract class ( AbstractContentView ) that will be extended by Content1.

AbstractContentView  will have common code and uiFilds (like buttons etc.)

Content1 will had himself to AbstractContentView using "setContentWidget(this);"

But I'm getting the following error:

"[ERROR] Method 'previous' can not be bound. You probably missed ui:field='uiPrevious' in the template."

Can anyone please tell me what am I doing wrong?

Thanks,

Luis.
