[flexcoders] Using view stack to link to mxml

[pankajarora_in]

I have a appplication abc.mxml
and there are 2 buttons but1 and but2 in it.
WHen I press but1 I need to call to anothe application 1.mxml
and when I press button 2 I need to call 3rd application 3.xml. Note
that pressing any button pass on data from abc.mxml to 1.mxml and
2.mxml. Any ideas how it can be done. I think viewstack can be one way
but any examples will be appreciated.
