Thanks for the really quick answer!!!
I can modify the script I include but I'd rather not. The calls of
"throw" are already wrapped in a function therefore your solution
could be envisaged.
There is another solution that works but I do not trully understand
why. I wrap the call of "new MyObject()" in a function defined in the
foo.js file :
function wrappingMyObjectConstructor() {
try {
return new MyObject();
} catch (e) {
throw e;
}
}
and calling wrappingMyObjectConstructor in JSNI works fine in IE. This
is a hack, it works, but does anyone know how to avoid this or can
explain this?
Thanks
