Hi all!
Was there a solution to this really strange ClassCastException already?
I have the same problem in the following circumstances:
public class Search extends BaseComponent
{
@Component
private Form simpleSearch;
@ApplicationState
private SimpleSearchString simpleSearchString;
private String searchTerm; // wil be populated by the form;
/* Form Handler */
String onSuccess()
{
if (searchTerm == null)
return null;
getSimpleSearchString().setSearchTerm(searchTerm);
return "ExtendedSearch";
}
public SimpleSearchString getSimpleSearchString()
{
return simpleSearchString;
}
This line gives the following stacktrace
java.lang.ClassCastException myapp.state.SimpleSearchString cannot be cast
to myapp.state.SimpleSearchString
Stack trace
- myapp.components.search.Search._$read_simpleSearchString(Search.java
)
- myapp.components.search.Search.getSimpleSearchString(Search.java:79)
- myapp.components.search.Search.onSuccess(Search.java:53)
- myapp.components.search.Search.handleComponentEvent(Search.java)
This happens regardless of if I access simpleSearchString directly or with
the getter.
Any idead what causes this somewhat puzzling behaviour?

Otho
