The @InjectState is declared inside of a component, and the injected state
object is referenced by the html code for that component during the
rendering of the page, inside a @Any component.
Html for component:
<li jwcid="[EMAIL PROTECTED]" ... >
<span onclick="prop:onClickJS" jwcid="@Any">
</span>
</li>
Java for component:
@InjectState("playerInfo")
public abstract HashMap getPlayerInfo();
public String getOnClickJS() {
return getSkinURL();
}
public String getSkinURL() {
if (getPlayerInfo().contains("key"))
return "...";
}
Once again this is happening only on 4.1.2 under Tomcat 5.5. It works for
4.0 and 4.1.1 under Jetty and Tomcat.
The only other thing that might not be standard is the use of the
tapestry-prop library and the "prop:" syntax instead of "ognl:'. But why
would it stop working in 4.1.2 but work in all previous versions of
Tapestry?

believe that having a single @InjectState method alone would cause that
error.
Where are you messing with the data that was injected?
