New issue 7 by [hidden email]: ILCalendarWidget broken in Pharo
http://code.google.com/p/iliadproject/issues/detail?id=7

What steps will reproduce the problem?

1. Implement the example shown in Nico Petton's blog post:
http://smalltalk.gnu.org/blog/nico/control-flow-iliad

2. Launch the example by setting the browser to  
http://localhost:8888/sequence

3.  The calendar appears on the browser page.  Select a new month in the  
dropdown menu, then
hit the 'Select' button.

Under Gnu Smalltalk, the calendar should update to the new month selected.  
Under Pharos, the
web application just hangs.  Interrupting the web page, or trying to reload  
the same URL
produces the following output:

http://code.google.com/p/iliadproject/issues/detail?id=7

The reason is that in GNU Smalltalk an "invalid" month like 0 or 13 wraps  
around to
the previous or following year.  Likewise, an invalid day wraps around to  
the
previous or following month.

For example #daysInMonthIndex:forYear: could be implemented like this

     ^(Date newDay: 0 monthIndex: m + 1 year: y) dayOfMonth
