Hi,
I would like to add the Dublin Core aspect to my Alfresco Sites.
As a template, I used one of Jeff Potts's gists (https://gist.github.com/jpotts/7242070).*
However whenever I add do this it messes up the site and Share too and they will not be accessible from Share.
The received error message is "Internal Server Error" (see attached screenshot);
Removing the aspect does not fix it, the site has to be deleted altogether.
Could anyone help fix this issue? I need my sites to have a couple of field which would be available in the Dublin Core aspect.
I'm using Alfresco 5.0c, OpenCMIS 0.12.0 and Java 1.7.
Please find my java code below:
Thank you very much in advance!

List<Object> aspects = site.getProperty("cmis:secondaryObjectTypeIds").getValues();
// Add Dublin Core aspect
if (!aspects.contains("P:cm:dublincore")) {
aspects.add("P:cm:dublincore");
HashMap<String, Object> props = new HashMap<String, Object>();
props.put("cmis:secondaryObjectTypeIds", aspects);
site.updateProperties(props);
System.out.println("Added aspect");
} else {
System.out.println("Doc already had aspect");
}
/*
Map<String, Object> newProps = new HashMap<String, Object>();
List<String> subList = new ArrayList<String>();
subList.add("P:cm:dublincore"); // Replace Dublincore String with Object
newProps.put("cmis:secondaryObjectTypeIds", subList); // multi-value property
site.updateProperties(newProps);
*/
}
Thank you very much in advance!

Hi,
Thanks for looking at my issue and sorry for the late reply.
So I've just redid the whole process (create site and add aspect).
Here is what I have in my alfresco.log
Thanks again!

A few additional information:
- If I add the aspect to the site manually from Share it seems to be working fine.
- If I add the aspect manually using the Apache CMIS Workbench it produces the same error.
So my initial presumption, that sites cannot have this aspect is false. They can, yet if I add it via CMIS something goes wrong.
Any Ideas?

Tested on version 4.2f with the same results, so it is not a version specific issue.

When you manually add the aspect then it will use Javascript action code, the other methods will likely use some other code. The problem is probably a value that is being set in one of the properties of the aspect added is "unexpected" by the FreeMarker template.
When Alfresco reports an error on jsonUtils.encodeJSONString(x) it is being disingenuous. The error is actually elsewhere in the output and jsonUtils.encodeJSONString(x) can't encode the output to a JSON string so it throws the error on jsonUtils.encodeJSONString(x).
To track it you need to comment out jsonUtils.encodeJSONString(x) and run the code and look at the output to see which property is actually causing the error, fix that and then uncomment out jsonUtils.encodeJSONString(x)
