I am working on an AIR application with 2 windows: One to create a new customer and another to display some information about the customer. On window 1, there is also a textfield to search for a customer by Id or name.
These are the steps to create a new customer:
with an "add" button on window 1, I open window 2.
on window 2, the user completes a form to create a new customer.
the information is saved in a MySQL Database over an HttpService.
The result handler method calls a public function on window 1:
result = "new wWin1().resultSaveCustomer(event)"
This part works well - the new customer Id is received.
In some cases, according customer data, I change the component color - this operation works well, if I load a customer after a using the search field, but if I search directly from the resultSaveCustomer function (after completion of step 3), a message appears:
Cannot access a property or method of a null object reference.
I don't understand why, because all the components in window 1, have an Id name! Or the property is a label with Id Name.
