  1. POkSOAP2 double ID exception
    text
    copied!<p>I am attempting to use kSOAP 2 in my android application, and when I try to perform a particular webservice request, I end up getting thrown a "double ID" exception. I was able to find where this gets thrown in the kSOAP source code, it is in the <code>SoapSerializationEnvelope</code> class method <code>public Object read()</code> Here is an excerpt from that code showing the exception being thrown: </p> <pre><code> if (id != null) { Object hlp = idMap.get(id); if (hlp instanceof FwdRef) { FwdRef f = (FwdRef) hlp; do { if (f.obj instanceof KvmSerializable) ((KvmSerializable) f.obj).setProperty(f.index, obj); else ((Vector) f.obj).setElementAt(obj, f.index); f = f.next; } while (f != null); } else if (hlp != null) throw new RuntimeException("double ID"); idMap.put(id, obj); } </code></pre> <p>I'm not at all sure what this exception is about, or how I can fix it. Anyone know what the deal with this exception is?</p> <p>Thanks</p> <p>Edit:</p> <p>It should be noted that I am also using a SOAP webservice connection method in the iOS version of this application, and the same exact request does not have any problems.</p> <p>New information:</p> <p>Upon closer inspection, the problem seems to be resulting from the xml response I am getting containing a <code>&lt;diffgr:before&gt;</code> element, which has tables with the same ID as above. I think this is the cause of the problem, the other requests I have performed up to this point do not have that element in them, and do not have the exception. So to add to the question: can I stop the webservice from sending this block in its response, or get kSOAP to ignore it?</p>
