It is general wizard problem. I don't know if scrollbars are best
solution. But at least left top corner should be visible in resized
wizard or minimal resizing size should be set.
Now left middle part of wizard is visible if you resize wizard to
enough small size.

Reassigning to openide/wizards for evaluation.

Wizard API has been designed that the main responsibility (for
layouting/sizing/a11y etc.) of the central pane of wizard has the
central component provider, e.g. web module for this case. So, Web
module could handle it if wants.

On other side, it's a common problem of almost all wizards, Wizard API
should help here. What about to place a provided component into
JSrcollPane instead of JPanel? Maybe helps. But, because we are in
late phase of NB4.1 release, this change is risky because could make
problems with visibility in some wizards.
I'll postpone it to promoF.

So what is the evalution for F?? Are we going to do something with this?

Fix of WizardDescriptor, r.1.12 should help. Scroll bars will displayed when needed.

The fix was rolled back. The wizard infrastructure doesn't support scrollbars as
default. Each panel should fit into window w/o scrollbar if a default font size
used. The infrastructure can use a scroll pane if non-standard font size is use.

Jirka is right: “Each panel should fit into window w/o scrollbar if a default font size used.”

From UI point of view the correct behavior should be:

i) default font size is used: each panel should fit into a window without scrollbars
ii) larger font size is used: the ideal state should be that a window would change its size so the panel 
can fit there without adding the scrollbars (by changing its size I don’t mean that wizard will change its 
size for every step). The max size of the window must be defined (e.g. screen resolution). When the 
maximum size of the window is reached and the panel does not fit there, scrollbars will appear. 

I guess it works for me.
