Sorry, forgot to mention that in WizardPage.tml should be a actionlink component
<a t:id="stepChanged" t:type="actionlink"/>
and the handler method should be
void onActionFromStepChanged(String toPage) {
_currentPage = toPage;
}
The Ajax request can be done:
new Ajax.Request('/context/wizardpage.stepchanged/step2', {
method: 'GET',
onSuccess: function (t) {
//really nothing to do here
}
});

Hi there!
Why not instead of a component the htmlFragment comes from a Page?, so in your
javascript code, you can make a page request.
For example, in my Main Page:
class WizardPage {
@Persist
private String _currentPage;
void onStepChanged(String toPage) {
_currentPage = toPage;
}
}
Then the javascript code can use that property to render the actual step.
new Ajax.Request('GET', ${currentPage}, {
onSuccess: function (transport) {
var replaceElement = $(...);
replaceElement.innerHTML = transport.responseText;
//load scripts as necessary.
}
});
${currentPage} can be a string that the ComponentResources generates, just a
detail that you already used.
And of course there should be a chain of pages to take in account.

Subject: T5: A component returning StreamResponse?
Hello,
I would like to create an ajax dialog (actually a series of them to act as a
wizard). The content of the dialog should change according to user
interaction and therefore create a series of steps. If this wizard is going
to have 3 steps then 3 ajax requests for dialog content would be made.
I would like each ajax request to call (different) T5 component returning
HTML fragment.
I am using jQuery to make a request
***** TEMPLATE ******
<script>
$().ready(function() {
$('#ex2').jqm({ajax: '${thelink}'}).jqmShow();
});
</script>
***** CLASS *****
public String getTheLink() {
Link l = _resources.createActionLink("myAction", false);
return l.toURI();
}
StreamResponse onMyAction() {
String htmlFragment = "<p>paragraph <b>bold</b></p>";
return new TextStreamResponse("text/html", htmlFragment);
}
I would like the htmlFragment to be generated by T5 component for example
WizardStep1.
If I declare a component in the class above:
@Component
private WizardStep1 wizardStep1;
and modify method onMyAction like this
StreamResponse onMyAction() {
wizardStep1.setMessage("hello");
return (StreamResponse) wizardStep1;
}
then I get Exception:
Component ui/dialog/JQModalAjax does not contain an embedded component with
id 'wizardStep1'.
which is true, as I don't have WizardStep1 in my ui/dialog/JQModalAjax.tml
Any suggestions?
