Hi All,
I am developing an application wherein i need to navigate among
different pages.
All these pages (page1, page2, page3...)are under viewstack.
I am navigating from page1 to page2 using
page2.addEventListener(FlexEvent.SHOW, abc);
viewStack.selectedChild = page2;
function abc(event)
{
page2.removeEventListener(FlexEvent.SHOW, abc);
}
And when I am in page2 and tried navigate to page 1 using
viewStack.selectedChild = page1;
The problem is here
now when i navigate from page 1 to page2 using
page2.addEventListener(FlexEvent.SHOW, abc);
viewStack.selectedChild = page2;
function abc(event)
{
page2.removeEventListener(FlexEvent.SHOW, abc);
}
i am getting an Error popup saying:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
