Hi Marco,
I would suggest adding your listener before starting the load of the
document.
Then you know for sure that the document hasn't finished when you add your
listener.
Also I should point out that getSVGDocument might return true before
the SVG DOM
is really ready to be used so just checking that could be bad you really need
to use the
LoadEventDispatcherListener.
Finally you need to make sure that you set the canvas to ALWAYS_DYNAMIC
otherwise you might not get the load event called for static looking SVG
documents.
