But why not make it possible to let us have a null contructor?
new ....Flash();
It creates an error today!
If I put "" (empty string) it works and then afterwards
setSource("flash path");
It is not logical in comparison to other widgets. What is your
rational here?

Hi Stefan,
sorry for the late answer, but we are at the moment in our release phase.
The Flash widget is a spacial widget. It has some properties, which can
not changed so easy after rendering. A change after rendering would
require a DOM manipulation, but updating a value for flash movies are
not possible. The only way to update a value is to remove the flash
movie from the DOM and create a new one.
But this have some side effect, for e.q. the Flash Player starts playing
the movie from the beginning and this will resetting the old state from
the movie. If you have for e.q. a charting solution. The developer have
to reconfigure the chart and synchronize the data manually.
I also don't know what's happens when for e.q. a old reference from a
movie is used to call method from the flash bridge. Is the new movie
called or does an error occur? If an error occurs the developer has to
ensure, to check the up-to-dateness from the reference.
You can see that it is not easy to write a general Flash widget
implementation which can be used for all use cases: simple movie
playing, e.q. charting or a two way (JavaScript and ActionScript)
communication. So we decided to keep it as simple as possible and this
has the restriction that some properties can't change after rendering.
I know that a property suggests that you can change it any time, but it
keeps the implementation as simple as possible. So it is not nice, but
it works as designed.
Cheers,
Chris
