PageParameters and BookmarkablePageLink
Hi,
I have a BookmarkablePageLink that I set parameters for it:
...
String configurationName = "conf";
ConfigurastionUser firstEntity = getFirstEntity();
PageParameters parameters = new PageParameters();
parameters.add("configurationName", configurationName);
parameters.add("firstEntity", firstEntity);
Link link = new BookmarkablePageLink("link", LinkAttributesPage.class,
parameters);
...
And in LinkAttributesPage, I have:
public LinkAttributesPage(PageParameters parameters) {
String confName = parameters.getString("configurationName");
ConfigurationUser user = parameters.get("firstEntity");
...
}
ConfigurationUser class is Serializable.
I get a ClassCastException for the firstEntity.
We use Wicket 1.3.6
Is this OK?
My solution is to have a constructor for that page that accepts the correct
parameters, but I want to know if it's a bug in the PagePArameters or if I
am misusing it.
Thanks

OK. I understand.
Yes, I prefer passing it as an object.
So I switched the page LinkAttributesPage to have a constructor that accepts
the OBJECTS I need.
If I ever need it with URL, then I'll add the PageParameters and will get
the objects by keys.
Thanks,

Hi,
the parameter value (a ConfigurastionUser in your case) is converted
to a String using
toString(). Are you sure that you want to pass in that object and not
an ID of it?
