Hi M. Mehta,
It is also working for me on your demo application. I did not change any permission. I'll check for errors, but I did not notice any. I'll also try to figure out the pattern of when it works versus when it does not.
Aside from this, I really like the software and we are planning to implement it in one of our manufacturing company. We will need to work on the french translation, as it is not really usable in it's current form.
Thank you
