document close handler not executing

Hi,

so I've created a document with various handlers open/close/print/save etc.

All of them are executing and the js is triggered except close document handler:

The handlers were added with this dictionary:

8 0 obj
<<
/DC 9 0 R
/DP 10 0 R
/DS 11 0 R
/WP 12 0 R
/WS 13 0 R
>>
endobj

The JS  for close looks like this:

9 0 obj
<<
/Type /Action
/S /JavaScript
/JS (
h = 99
app.alert({cMsg: 'close PDF', cTitle: 'Testing PDF JavaScript', nIcon: 3});
)
>>
endobj

Also another interesting thing I noticed is that the scope is shared between all these handlers. If I set a variable somewhere it's visibile in all the handlers. In which case I can set variable/functions in open and call them everywhere......
