Description Geertjan Wielenga 2005-09-26 13:15:05 UTC 
Create module project, then use the New Wizard wizard. In the 1st panel, type
'1000' (or some other high number, I don't know which number is the lowest
acceptable number) in 'Number of Steps'. Click Next. Wizard freezes, IDE hangs,
big deadlock, and then I needed to force the IDE to close.
Comment 1 Martin Krauskopf 2005-09-26 13:32:10 UTC 
It is a real deadlock or just a lot of work needed to be done in the EDT? If
later, than P4. 1000 is quite a lot.
Comment 2 Geertjan Wielenga 2005-09-26 13:37:52 UTC 
Well, I just created without any problem a wizard with 50 steps. I don't think
there are many users (maybe even none) who will want as many as 50 steps. 

So, for me, the problem is not that there aren't going to WANT to have 1000
steps, but maybe some who will accidently put too many 0's (instead of typing in
'10' they might type in '100' or '1000'). This is when the problem might happen.

But, if you think this isn't very likely, then this could also be a P4.
Comment 3 Martin Krauskopf 2005-09-26 13:44:28 UTC 
I think that this "typo" is almost impossible. Actually typo itself is possible,
of course. But than you click "Next" button. The time to get to the second panel
is always the same, no matter how much steps you have entered. Then you enter
the class name prefix and... ups. Neverending list of panel classes is generated
into textarea of created files. So here everybody would probably stop. Yes,
except you, me, Petr Zajac, ... who are testing it :) But definitelly would be
nice to fix.
Comment 4 pzajac 2005-10-18 18:20:29 UTC 
So please don't open all the generated files in editor. 
BTW it is responsivness problem when you generate wizard for more steps (10 ..).
Comment 5 Martin Krauskopf 2005-11-04 12:47:48 UTC 
> So please don't open all the generated files in editor... responsiveness problem

True and good idea. I'll constraint it to magic number 10... However I will not
constraint the user in what he is doing.
Comment 6 Martin Krauskopf 2005-11-04 13:00:14 UTC 
Fixed.

Checking in ui/wizard/BasicWizardIterator.java; 1.16 --> 1.17
Comment 7 Tomas Danek 2005-11-04 13:54:03 UTC

I'll attach...

Comment 9 Martin Krauskopf 2005-11-04 14:08:07 UTC 
Has nothing to do with apisupport (we tried it with Tomas and cannot reproduce
with fresh build).
Comment 10 Tomas Danek 2005-11-09 15:11:28 UTC 
Yes,NPE was consequent of P1 issue. This was fixed ok. Verified.
