I returned to main task today. It was a good idea to disconnect myself from the task the day before – I was able to take a distance look on my problems. Yap, that being said, I had a hard time today trying investigate how out project web framework is working – with all this flow control, JavaScript around. I tried many different approaches to avoid exceptions, to allow flow working – once again I filled lost! Anyone I took the best possible solution – I asked my teammate for help, for his idea how to solve that. He didn’t give me a direct solution, but he figured out some points that I never thought about!
At the end of day I had working solution, that didn’t break anything – it was quite simple (if I look on it now 
) – I just implemented the whole download logic in separated Struts action, not connected with the internal framework – that allowed me to skip the problems!
The last thing to do is write a unit test to confirm that!
