I'm developing some complex GUI app using the Flex builder 3 (eclipse plug in) and while i was working i suddenly got a blank screen when i ran my application.
no error was printed out in the consul. it appeared that flex was loading but wasn't loading my application.
if this happens to you too, check your code to see if you are embedding a file as XML:
[Embed(source="...data.xml")]
private static var xmlData:Class;
if you are, and the file happens to be malformed (some mistake in the XML structure) you are not going to see any error from the compiler or the runtime(!)
just a peaceful, zen like, blank page.

Is it a bug? Is it a plane? no.. its...
last night i found a very interesting bug while running the debugger in the flex builder (version 3)
I tries to compare an XML typed object to an empty string, don't ask me why.
the debugger was watching the expression (dataSource=="").
i then noticed that when the variable dataSource was not null, and actually contained a valid XML object; the debugger was evaluating a false result in the watcher while in the code, the result was opposite.
i caught a screen shot of this anomaly:
