Hello guys,  
I tried to use rtex to generate pdfs, and it worked fine.  
Then I tried to use render\_as\_string to I could have the pdf data and  
put it somewhere (specific) in my hard drive, but for some unknown  
reason (at least for me :D) the result of render\_as\_string is always (if  
the action is valid) nil…  
I’m using rails 2.0.2

Any ideas?

Tks in advance,  
jose
