I'll check out the latest from SVN and give it another try.

To try to put my problem into context:

I'm actually wanting to call down into the Quicktime API as QTJ does not have QT7 API functions in it. I'm actually wanting to mute/unmute individual channels. This is done by sending a property to the track which contains the channel(s) to mute. At compile-time, the number of channels in a given track is unknown. So the I need a variable-length array of ChannelDescription structs inside the TrackProperty struct.

i.e.

public class TrackProperty extends Structure { public int numofchannels; public ChannelDescription[] descriptions; }

public class ChannelDescription extends Structure { public float volume; public float[3] position; }

(obviously these are simple mock-ups and not the actual structures, but give you a better context)

So, assuming I unhollow/initialise these fully, the .size() method should give me a size as this is actually an argument into the Native function I am calling.

Initially it did not. I will try the latest SVN and let you know soon. If it does fail, I'll do another more realistic test.

Thank you for your help!
