now i work with non visual components, the detail that it works fine the first time, send the pdf correctly, but if I try several times, the second time fails or until the fifth, then it does nothing, it is like dataset is disconnected, because I try to change of record and does not work, but does not generate any error in the log...
one more thing, if I run the application with the option localhost everything works fine, no matter how many times I try, but if done through the dll on the server is when the problems are generated... I will have to change something in the configuration of apache? ...
