I'm glad other folks are having the same issues. And thanks for the
feedback.
I'm hesitant to modify Tapestry classes. Then I might have to worry about
unexpected impacts of changing the code and maintainability with updates.
The work around im using.. but don't like all that much is to use the
@InjectObject method as just a template to get a handle to the right class.
Then creating a newInstance to work with on the page.
@InjectObject("spring:Person")
public abstract Person getPersonTemplate();
public abstract Person getPerson();
public abstract void setPerson(Person person);
public void pageBeginRender(PageEvent arg0) {
if (getPerson() == null) {
try {
setPerson(getPersonTemplate().getClass().newInstance());
} catch (InstantiationException e) {
...
} catch (IllegalAccessException e) {
... }
}
}
....
public void detach() {
if (log.isDebugEnabled())
log.debug("Page Detaching");
setPerson(null);
super.detach();
}
I wouldnt call it the most elegant code and I hate having to try/catch now.
Maybe a better alternative will come down the road.
