Hello all,
Recently, i decided to play a bit with shale. I began to write some
tests jsp to play with it. I came across various problems/interrogations:
1) considering the following dialog configuration, and the following
jsps (see bottom of email), i am supposed to have one main dialog, with
a button starting a subdialog to edit one specific value.
More precisely, the backing bean of main dialog is a property bean
which gets modified by the subdialog. I can start the dialog ok with
<h:commandLink value="start..." action="dialog:Test Dialog"/>, i enter
the subdialog when i click the appropriate button in testMain.faces but
i am stuck in the subdialog. I never return from it. Did i miss
something in the way a dialog is supposed to end? There is no message in
console to help and in subdialog i click on an action which's outcome
should direct to and <exit ...> of subdialog.
2) I plan in an app to have the following structure:
- have a 'main' dialog present some forms to the user to edit a bean X
containing some properties.
- amongst properties of X there is a collection of element Y, those
elements are complex beans which will be presented read-only
- i need, next to those elements Y to put a button starting a subdialog
for edition of Y.
- How do i pass the element Y as a parameter to the subdialog for edition?
- Will the content of my main dialog be preserved during the run of
subdialog?
3) While testing, i noticed if i start dialog A by clicking on an action
'dialog:A', enter a subdialog B, redeploy the webapp, click again on
action 'dialog:A', i get exceptions in console telling me "You have
requested a transition outcome named "dialog:A" from a state named
"xxxx" in a dialog named "B", but no transition definition can be
found. Double check the spelling of the transition outcome name. To
circumvent this problem i need to remove my jsessionId cookie, reload
the page containg the link to action, and the i can start dialog:A. Why
isn't dialog:xxxx always assumed as an attempt to start a new dialog and
drop currently running one?
4) is there a way to start a dialog process or create a link to a JSF
page without ressorting to a <h:form><h:commandLink... construction?
(like http://........?action=dialog:xxxx or
http://..../userDetails.faces?username=xxxx), all this to prevent the
use of javascript when possible and allow the sending of direct link to
some JSF content by email.
Greetings,
David Delbecq
