Hi,
If you want to call a method of the parent MXML, dont create a new instance
of it (like you have done by creating a new instance of WhatsOnAdminView.)
Just refer to the method using "parentDocument". So just remove the code
where you instantiate the variable "obj". And change the line
"obj.cmdView_click()" to "parentDocument.cmdView_click();".
Regards,
Venkat
