Scott, may be, there is a little misunderstanding. My question is not about debugging and reverse engineering, but about general approach. I am trying realize example from "official" Trinidad's page. At least, I am considering as official. Am I right?
http://myfaces.apache.org/trinidad/trinidad-api/tagdoc/tr_fileDownloadActionListener.html Usually, such examples give a good base to start with more deep development. In this case, it is no. This example doesnot cover complete solution, or obsolete, or belongs to other version. I have not time to explore ans investigate basic elementary construction, it is not a subject of research for programmer. May be, I am wrong or my understanding of myfaces.apache's policy is incorrect? I dont know which tag is giving the problems, because I dont see any action after clicking on commandLink or button, inside form or outside. Also I dont see any exceptions/messages form Tomcat.
