I'm getting a ClassCastException when using the JXTemplateGenerator and passing
bizdata to it:
java.lang.ClassCastException
at org.apache.cocoon.components.flow.javascript.ScriptablePropertyHandler
.getPropertyNames(ScriptablePropertyHandler.java:77)
at org.apache.cocoon.generation.JXTemplateGenerator
.fillContext(JXTemplateGenerator.java:2410)
at org.apache.cocoon.generation.JXTemplateGenerator
.setContexts(JXTemplateGenerator.java:2457)
at org.apache.cocoon.generation.JXTemplateGenerator
.setup(JXTemplateGenerator.java:2397)
It's an older version of Cocoon (2004-06-29):
http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/src/java/org/apache/cocoon/
components/flow/javascript/ScriptablePropertyHandler.java?annotate=1.7
http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/src/java/org/apache/cocoon/
generation/JXTemplateGenerator.java?annotate=1.50
In this code some properties are casted to Strings:
69 : Object[] ids;
70 : if (obj instanceof ScriptableObject) {
71 : ids = ((ScriptableObject)obj).getAllIds();
72 : } else {
73 : ids = ((Scriptable)obj).getIds();
74 : }
75 : String[] result = new String[ids.length];
76 : for (int i = 0; i < result.length; i++) {
77 : result[i] = (String)ids[i];
78 : }
But obj is a NativeArray in my case and ids after running through line 71
contains an Integer 0 and a String "length".
The flowscript code looks like the following:
var legalcasesArray = new Array();
for (var i = 0; i < legalcases.size(); i++) {
var lc = legalcases.get(i);
var event = lc.getEvent();
legalcasesArray[i] = {"document": event.getDocument(lc), "variant":
lc.getDocumentVariant(), "eventId": event.getId()};
}
cocoon.sendPage("internal-display-document-bulk", legalcasesArray);
Everything works like expected, I only get this exception stacktrace printed on
the console as the exception is ignored. Is there an error in using JXTemplate
or is it a bug?
