The comment <!-- The current presetnation view object --> is not quite
in line with the actual behavior. When you call the getter in your page,
hivemind creates an instance of your class for you; you cannot set a
session scope object, you can only get it (and if it does not exist it
is created).
A simple workaround is to make UserSession class with a presentationView
property in it that you can set and get.

Hello all,
I am using the ASO (Application State Object) feature of Tapestry 4.
Mostly it is working very well. I have a problem with one property
though that seems to require special handling that my other ASOs don't.
I have in my hivemind.xml:
<module id="ices" version="1.0.0">
<contribution configuration-id="tapestry.state.ApplicationObjects">
.. other ASOs that seem to work fine...
<!-- The current presentation view object -->
<state-object name="presentationView" scope="session">
<create-instance
class="com.ingenix.freya.api.presentation.metadata.PresentationView"/>
</state-object>
</contribution>
</module>
Then in my Java file for the page that uses this:
@InjectObject("presentationView")
public abstract PresentationView getPresentationView();
public abstract void setPresentationView(PresentationView pPv);
I have to call the setter from a method that is called from a trigger
method in a feeder page to initialize the view object (presentationView)
used by the page.
The problem is: when I hit the page I get a ApplicationRuntimeException
Property presentationView should be read-only; remove method public
abstract void
com.ingenix.freya.web.pages.presentation.PresentationDataPage.setPresent
ationView(com.ingenix.freya.api.presentation.metadata.PresentationView).
I need the view to be an ASO because it used on other pages that cascade
from this page (popups, etc). Passing it around would be cumbersome.
Any clues as to why it chokes and needs to be read-only?
