New issue 857 by [hidden email]: ROCircle strange MNU #extent:
http://code.google.com/p/moose-technology/issues/detail?id=857

With ConfigurationOfRoassal.667 just loaded, my project application popped  
up a 'MNU: receiver of "extent:" is nil, but as you can see in the attached  
screen snapshot, which has the default debugger highlighting showing the  
current executiong, the receiver is the ivar 'next' which is actually _not_  
nil, but an instance of RONullShape.  Strange...

As a test case, executing the following in Rossal Easel caused the same MNU.
=========
rawView add: (ROElement on: 1) + ROCircle.
=========

Fixed it  with: Compiler recompileAll. This actually has happened to me a  
few times in past couple of weeks.

(Note actually the example code gives a really tiny circle and #spriteOn:  
would have been better than #on:)

Also, something has happened to ROCircle that it is no longer constrained  
to be a circle.  The aim of this was so when the text of an element got  
wider or higher, the other dimension followed to maintain the circle within  
which the text was centred.
This was working in Roassal-AlexandreBergel.352, which you can see with the  
green ConnectivityNode circles in my project application that I previously  
uploaded the image to [1].  If you update that image to Roassal.363  
(ConfigurationOfRoassal.667)
then the circles are flat.

I have found two bugs in the way ROCircle is implemented. Maybe you have  
bumped into these...

Ben, do you still experience that problem?

A can't reproduce the MNU.  I don't think that was a Roassal problem.  
Seemed like something unstable in the system but I couldn't pin it down.  
As per the title fo this ticket, it should be closed.

However I still note that the following in Easel does not produce a  
circle :P
x := (ROElement on: 1) + ROCircle.
rawView add: x.
x height: 100; width: 200.

(Sorry) to be explicit, "Circles" should be constrained to remain a circle  
when either dimension is changed.

ROCircle was renamed to ROEllipse.
