These are questions I have regarding the tutorial. They may be answered later
in the tutorial (in fact I know some of the answers now), but they caused
confusion for me while I read the tutorial because they were unclear at that
time.
Although I'd like to get answers in this forum, my goal was to give you some
feedback on the tutorial document from someone with no JSF/EJB3/Seam experience.
Section numbers are from the PDF version of the "Reference Manual" with the
tutorial embedded in it.
Section 1.2.2 ("How it works") I'm confused about the initial rendering of
the register.jsp page. What is the entry point? That is, the index.html
forwards (redirects?) to a "register.seam" url. How does it know to
render/display the JSP file? Does it just look for a jsp with the same name?
(I can't find any references to "register.jsp" in any files in the project, so
I'm assuming it's magic.) If I had wanted to go to a java bean first, before
displaying the JSP, what url would I have put in the index.html file.
Section 1.4 (ToDo list) I'm just generally confused about how the jsp gets the
correct set of tasks from the list of tasks. There seems to be some magical
component named "taskInstanceList" that isn't referenced anywhere in the code
except for the todo.jsp file. It somehow has a list of only the "todo" tasks,
but what would happen if there are other process definitions? For example, the
login.java login() method goes directly to the todo.jsp page, without any
reference to a particular process definition. Then the jsp page grabs what
appears to be the list of all tasks...
Also, the "update" action referenced from the JSP - what's up with that? Is
that a magic action? Is it just refreshing the jsp page or is there something
else happening?
Incidently, it's annoying that the previously added todo item stays in the
input field. While I can see why that happens, I presume that since I'm not
using an instance variable on my action bean I can't set it to null after the
"createTodo()" method.
Sigh - I assume that all this will be cleared up in later examples - I'm just
frustrated by the unkowns.
Section 1.5 - I noticed that I can submit the page by hitting the enter key but
it just reloads the page. Interestingly, it sort of submits the form, as it
updates the "higher/lower" display. However, it doesn't update the other
messages or the number of guesses remaining. I think that means that it's
updating my bean's attributes based on the form inputs, but not calling the
"guess" method. I assume there's a way in JSF/Seam to handle the form
submission via the enter key, since it's a common feature of webapps.
