发帖数: 1342 | 3 You are right. I'm still new to this jsf business. I think the code I'm
working on is a bit old (not jsf 2.0).
To be honest, being new to this java front end, I felt understanding the
whole work flow of web is difficult, if not mystery.

are 100 different frameworks and none of them kills.

发帖数: 1342 | 5 Encountered a similar problem recently. I have two components: one drop down
box, and one text field, was using JSF RichFaces (a4j support) for
implementation. When the user select certain value (ValueChangeListener), I
want to make the text field visible and input value there. The show/no show
part works ok, the problem was the input value was never updated. After we
use this "saveState" thing to save the flag for show/no show, it worked.
It seems the problem was due to the request scope, "SaveState" for the flag
makes it more like view scope.
