Call methods to closed window

[kim at martel.com.au]

In OS10.2 I have a problem when I try to call back a method (item reference)
in a window that has closed it causes code to stop and in run time closes
all windows with error 

 

Do iCallBack.$setAttachments() Returns #F

Close window instance [$cwind().$name]

 

Where iCallBack is item reference to window instance.  

 

Normally window is open so no problem.  If window is closed accidently the
active window cannot call method the method before it closes.

 

I can avoid this by testing if window instance is still open before calling
the method.

 

Can you calculate a character from an item reference so you can then
calculate the iwindow name.

 

iCallBack = Reference to $root.$iwindows.wExam_633

 

If I can calculate a character as wExam_633 I could test to see if Window is
open before calling method to prevent the error

 

OR is there another better way
