Select component

[Helen Zaks <he...@virtualtourist.com>]

 Hello,
I'm having an issue with the tapestry Select component.  According to the
Select component example for Tapestry 4.0, 'selected' binding of the Option
Component should be bound to a boolean array.  Everything works fine when
the component first loads on the page. I initialize the boolean array in
prepareForRender(IRequestCycle cycle).  However, when I submit the form, I
get a null exception on the page before the submit method or
prepareForRender() are even called.  If the prepareForRender() or the
Submit() aren't called before the exception is thrown, how do I event check
for a null to prevent the exception?
This is the exception I'm getting....
Unable to update OGNL expression '<parsed OGNL expression>' of
$EventEdit_36@1e3f171[Test/$EventEdit] to false: target is null for
setProperty(null, "0", false) binding:
ExpressionBinding[Test/$EventEdit hoursSelection[currentHoursIndex]]

Thanks for your help.
Helen
