Hi,
I'm using the Apache Camle version 2.14.0 and have found some trouble
about the camel-jcr with JCR_GET_BY_ID when the node contains multi-valued
property as [1].
I also have a chance to investigate to the camel-jcr source code, the
org.apache.camel.component.jcr.JcrProducer, and found that it use the
following:-
if (JcrConstants.JCR_INSERT.equals(operation)) {
...
for (String key : headers.keySet()) {
Value value = converter.convertTo(Value.class,
exchange, message.getHeader(key));
...
}
...
} else if (JcrConstants.JCR_GET_BY_ID.equals(operation)) {
...
while (properties.hasNext()) {
Property property = properties.nextProperty();
Class<?> aClass = classForJCRType(property);
Object value = converter.convertTo(aClass, exchange,
property.getValue());
...
}
} else {
throw new RuntimeException("Unsupported operation: " +
operation);
}
Please correct me if I'm wrong. Since the code uses the Value.class
and property.getValue() which is for the non-multi-valued. Does it mean
that the camel-jcr does not provide the support to the muli-valued?
Do we have any workaround for supporting the multi-valued? At the
moment I consider to replace the JcrProducer with my own interim fixing.
Anyhow I thought that it may not be a proper way and would like your help
to advise further?
Thank you very much for your help in advance. I'm looking forward to
hearing from you soon.
Best Regards,
Charlee Ch.
