Layout assistants are available for some of the complex GXT and GWT Ext layouts.

The standard GWT panels don't have any as they don't need them.

maybe THEY don't but i do, i've been spending the entire day just trying to use a uibinder  place a label and a text box inside a caption panel, and make them look staright, and i couldn't do i,i allready understood captionpanel, only contains one widget, so i tried using the layout panel inside it, which made the text box look weird, and flow panel which didn't allow me to place rows. not to mention horizontal panel which doesn't even work in standard mode

and between switching from source to design view (which takes around 60 seconds, i guess it has to compile the whole project), how hard could it be to design a regular application form, without using aboslute panel.

we have 3-4 days to show proof of concept of running a few screens.

i've been trying to use grid, but it acts funny in the designer of the ui binder.
