[JBoss Seam] - Re: Strange behavior of jar file loading
by pierospinelli
Sorry, actually I was very generic: I am using a custom tag-library (working on previous seam version).
I had the error during home page loading: I checked the class "com/sun/facelets/tag/AbstractTagLibrary" is present in jsf-facelets.jar unde WEB-INF/lib.
This is the lib code and stack trace fragment:

[JBoss Seam] - Re: Login Redirection not propagating GET parameters
by pete.muirï¼ jboss.org
"milli" wrote : Let's forget about propagating parameters values for a while. But when it comes to just passing GET parameters(to the backing bean component) shouldn't they be having the same behaviour?
|
| Here is what I found out.
|
| When you have the parameter defined in pages.xml, here is the flow of the backing bean component:
|
| * Seam calls @Create method first
| * It then calls setters on the parameters to initialize the values
|
| With @RequestParameter, the behaviour is
| * Seam injects parameter values first (No need to have setters)
| * It then calls the @Create method
The behaviour you describe is consistent through Seam. @RequestParameter does injection (which of course occurs before @Create but after the constructor), page parameters set model attributes (which occurs after the constructor and @Create). Spend some time understanding what injection is and what page parameters are.
