Blank page when spliting in 2 java classes.

I’m just starting developing with gwt/smartgwt.

I have created a simple form inside a layout and it was being shown accordingly.
When I decided to split the code in 2 classes, a blank page is shown.

I only created a new class and inside its constructor I put all code related to the form construction, I also created a method to get the form from outside.
At the original class, I simply called new() for that class and getForm() inside the layout.addMember method.

After all, off course, layout.draw();.

Does anybody knows the reason?
