Empty date value

[Phil Bingley <Ph...@tvnz.co.nz>]

Hi,

I am just trying to get my teeth in to things and I have a problem with
a Date value in a custom node type that I have created.

My type is defined as follows

<exp = 'http://bixby/test'>
[exp:article] > mix:referenceable
- exp:title (string) = '' mandatory autocreated
- exp:created (date) mandatory
- exp:body (string) = '' autocreated
- exp:related (reference) multiple


I add content like so

Node test = content.addNode("Test Node", "exp:article");
   test.setProperty("exp:created", Calendar.getInstance());
   test.setProperty("exp:title", "Its a test title");
   test.setProperty("exp:body", "blah blah blah");

then can output the content and all is fine (using the dump() method
from the First Hops doc)

If I run the application again, having removed the code to add the node,
I get the following exception when trying to dump() the content. 

javax.jcr.ValueFormatException: empty value
at
org.apache.jackrabbit.value.DateValue.getInternalString(DateValue.java:1
14)
at org.apache.jackrabbit.value.BaseValue.getString(BaseValue.java:207)
at
org.apache.jackrabbit.core.PropertyImpl.getString(PropertyImpl.java:525)

I have verified that the date is stored in the data (XMLPersistenceMgr)
and have tested with the Derby PM as well - same result.  So there seems
to be an issue of some sort when loading from the store I guess.
Anyone have any ideas on this one?

Thanks,
Phil

i tested with the following code fragment:

            String nodeName = "Test Node";
            Node test;
            if (!root.hasNode(nodeName)) {
                test = root.addNode(nodeName, "exp:article");
                test.setProperty("exp:created", Calendar.getInstance());
                test.setProperty("exp:title", "Its a test title");
                test.setProperty("exp:body", "blah blah blah");
                root.save();
            } else {
                test = root.getNode(nodeName);
            }
            dumpTree(test, System.out);


i was unable to reproduce the problem you described. are you accessing the
repository through rmi? if the problem persists please provide the complete
stack trace and a complete simple test program (incl. your configuration etc).

cheers
