Why there is two "type": "dng_module:Binding" in JSON when retrieving a Module structure?

Pierre Bentkowski (61●5●14) | asked Mar 19 '18, 2:08 p.m.

I used the following to retrieve the Module structure:

private JSONArray getModuleStruct() throws Exception {
        String structureURI = this.moduleURI + "/structure";
        HttpGet get = new HttpGet(structureURI);
        get.addHeader("DoorsRP-Request-Type", "public 2.0");
        get.addHeader("Accept", "application/json");

        HttpResponse response = HttpUtils.sendGetForSecureDocument(clm_props.getServerURL(), get, clm_props.getCLMlogin(), clm_props.getCLMpassword(), httpclient, clm_props.getJazzURL());
        if (response.getStatusLine().getStatusCode() != 200) {
            response.getEntity().consumeContent();
            throw new HttpResponseException(response.getStatusLine()
                    .getStatusCode(), response.getStatusLine()
                    .getReasonPhrase());
        }

        String moduleStr = EntityUtils.toString(response.getEntity());

        response.getEntity().consumeContent();
        JSONArray jsonArray = new JSONArray(moduleStr);

The new JSONArray(moduleStr); fail because the Strign contains two times the "dng_module:Binding"

[{
"uri": "https://almtest.rtp.raleigh.ibm.com/rm/resources/_a7V9wSiTEei0FZBpM_jKog/structure",
"type": "dng_module:Binding",
"component": "https://almtest.rtp.raleigh.ibm.com/rm/cm/component/_77fFICenEei0FZBpM_jKog",
"type": "dng_module:Binding",
"isStructureRoot": "true",
"module": "https://almtest.rtp.raleigh.ibm.com/rm/resources/_a7V9wSiTEei0FZBpM_jKog",
"boundArtifact": "http://www.w3.org/1999/02/22-rdf-syntax-ns#nil",
"childBindings": ["https://almtest.rtp.raleigh.ibm.com/rm/resources/MB_8bc272efe08d43bab784d0f221390fee", "https://almtest.rtp.raleigh.ibm.com/rm/resources/MB_00d017f1e253498c9b28fc71efc5bc95"]
}, {

Is the issue is the JSONArray too scrict, or the API is generating the extra "type": "dng_module:Binding" by mistake?

I have confirmed this is a defect. I have opened the following work item to track: Public Module Structure representation returns 2 "type" entries for root Binding.

I try it in my own environment with both DNG 6.0.5 and 6.0.5 iFix003a and can see only one line of "type" : "dng_module:Binding" for each element, except for the root element. So it does appear to be a defect.

Do you use any other headers then those?

get.addHeader("DoorsRP-Request-Type", "public 2.0");
get.addHeader("Accept", "application/json");

I use the same headers. I have edited my response as I can actually see the same symptom.

Work around:

Prior to call
JSONArray jsonArray = new JSONArray(moduleStr);

I clean the String

String pattern = ".dng_module:Binding.\n";
moduleStr = moduleStr.replaceFirst(pattern, "");

I still think the response should be clean

It's all about the answers!
