ZBTxRequest doesn't work properly on ZB S2B chips

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Program two arduinos (coordinator and router) with ZB examples from the 
library (receive and send).
2. Let them to associate themselves.
3. Look serial monitor for received data.

What is the expected output? What do you see instead?
The data send by the router. Nothing, the coordinator doesn't receive anything.

What version of the product are you using? On what operating system?
I'm working with ZB S2B on Arduino Mega2560, with the latest ZB library (API 
0.9).

Please provide any additional information below.
- I tried making the frames by myself and send them by x-ctu software, and it 
works fine!! Also the checksum is right. 
- Moreover, I send the handmade frame by x-ctu (from router) and I receive it 
(to coordinator). [I have problems showing the entire data, but this is my 
fault).
- In the other way, sending data with API and receiving it without it, it 
doesn't work.

I can't find what is the code problem.
