Hello Martin,
Thank you for the swift reply.
I added the call at the beginning of my constructor but that doesn't seem
to make any difference in the application. When the page loads the
url still shows the
?wicket:bookmarkablePage=:com.ourstuff.PatientSelectionPage. That url
remains throughout the AutoCompleteTextField selection process that
triggers a Form onSubmit and a AutoComplete component onSubmit event.
setStatelessHint(*false*);
System.*out*.println("is page stateless: " + isPageStateless());
Console shows: 11:56:33,898 INFO [STDOUT] is page stateless: false
As I mentioned in my original description, once the AutoComplete field is
populated with a name, if I place the cursor in the AutoCompleteTextField
and then hit the Enter key only the Form component's onSubmit is triggered
(as I would expect) and the page is versioned. This is the behavior I
would LIKE to get from the AutoCompleteTextField selection.
For my better understanding, why are the two Form onSubmits different and
because they do seem different, can I force the
AutoComplete/onchange/onsubmit event to behave like the Field level Enter
key event and force a versioning of the page?
I have another page that uses a PageableListView that behaves the same way
(no page version created). I would like to version each navigatable page
so when a user clicks a link from say page 4 of the PLV I would like them
to return to page 4 on a Back button press.
Thank you,
Craig
ps. I will see what I can do regarding duplicating the issue in 6.16 but
upgrading our current environment is not an immediate option.
