Hi Dave,
The class cast exception comes from a line of code that's new to
2.8.1. that code was added for SAK-20450. See line 170 here:
paramsMap.put(FormHelper.XSL_ARTIFACT_ID,
((Artifact)bean).getId().getValue());
http://source.sakaiproject.org/viewsvn/metaobj/trunk/metaobj-util/tool-lib/src/java/org/sakaiproject/metaobj/shared/control/XsltArtifactView.java?r1=91943&r2=91944&
It looks like there's an if-else before the new line that checks if
ElementBean bean is an Artifact before casting and calling getId().
if (bean instanceof Artifact) {
root = getStructuredArtifactDefinitionManager().createFormViewXml(
(Artifact) bean, null);
homeType = getHomeType((Artifact) bean);
edit = ((Artifact)bean).getId() != null;
}
else {
... //Another way to find the id of the artifact
}
Maybe some of that conditional logic should be duplicated, or maybe
the XSL_ARTIFACT_ID parameter could be set within that if-else instead
of after it.
