Hi,
So, I have a generated Seam app, and we have placed a combo box and a button on
top, near the "login" part (inside the loginout.xhtml file).
The button calles a method, which has the @Begin annotation.
After I login, I choose a value from the drop down and press the Change button.
This will place some objects on the Conversation context.
i also removed the propagation="none" from the s:link elements, so now i can
move around with the setted values. But if I change the value for the second
time I get an exception about calling begin from inside a conversation, with
hint that I should use (join=true).
So, here is what needs to work, and what is happening:
I need to allow the objects that are placed on context to exist in 2 different
conversations, that is, if the user logs in, and sets the values from the combo
to X & Y, and then opens a likn in another tab/browser, having the same
session, he should be able to select from the combo a different option and work
in both browsers concurently, with different values placed on the conversation
context.
But, this is what I get:
1) If I place @Begin on the method that is called from the interface when
changing the value, when I change the combo value from either of the windows I
get an error, with the above hint.
2) If I use @Begin(join=true), then both windows will use the same
conversation, that is, if I change from the combo in window 1 and then navigate
somewhere else in window 2, the values from the conversation context will have
the same values as those set in window 1
3) If I use for example this code, then it's like @Begin is not called:
//method called to change the value.
| @End
| public void changeSelected()
| {
| doStuff();
| }
|
|
| //method called from first one.
| @Begin
| public void doStuff()
| {
| //...
| }
4) The same if i use this to close the existing conversation and start a new
one:
//method called to change the value.
| @End
| @Begin
| public void changeSelected()
| {
| doStuff();
| }
|
|
| //method called from first one.
| public void doStuff()
| {
| //...
| }
Am I missing something here? How do I end the conversation only when I want to
change the value???
