Hi,
I'm quite new to iPOJO and I'm facing an issue with composites.
I've attached a metadata.xml which, I believe, is self-explanatory. When I
try to instantiate the declared "composite-external" (using Factory api), I
get a StackOverflowError, which is attached too.
The junit test is also attached.
This is probably my fault... any clue anyone?
Thanks in advance,
Thiago Souza
