Strange Datagrid Column Problem

[Peter Haworth]

I've customised a datagrid column to contain a checkbox.  Right after  
the customisation, the checkbox shows up in the column just fine.  I  
then added the following line of code in the FillInData handler for  
the column:

set the hilite of button 1 of the long ID of me to handleBoolean(pData)

.. and I get the message "an error has occurred in behavior for the  
column template: Object: can't set this property.

I've used this same code in other datagrids to handle checking and  
unchecking check boxes and it works fine.

So I stuck an answer information right before that line of code to  
display the name of the control just to make sure I was looking at the  
correct control:

answer information the name of button 1 of the long ID of me

The display shows the correct name for the check box but it says it is  
a field, not a checkbox so no wonder it can't set the hilite property!

Any ideas as to how my checkbox got to be a field?  And even more  
puzzling, how does the display of the name of a button show it to be a  
field?
