Subject AW: Problems referring to elements in s:Window using code behind pattern
Date Thu, 18 Feb 2016 15:40:54 GMT
Hi Alex,

thanks for your quick reply!
The issue was resolved - just saw that the AS class was instantiated in the related code for
creating the windows instead of the MXML.
Stupid mistake, sorry for the inconvenience!

Betreff: Re: Problems referring to elements in s:Window using code behind pattern

If an instance is state-dependent (includeIn, excludeFrom), then it might not be there at
creationComplete, but otherwise it should be.  Just as a test, try setTimeout and/or click
a button that calls that code to prove it really is a timing issue.  It could be something
else.
