Added this block of code to oryx.debug.js and works fine:

<code>
if (!Document.prototype.createAttributeNS) {
Document.prototype.createAttributeNS = function(namespaceURI, qualifiedName) {
    var dummy = this.createElement('dummy');
    dummy.setAttributeNS(namespaceURI, qualifiedName, '');
    var attr = dummy.attributes[0];
    dummy.removeAttributeNode(attr);
    return attr;
};
}
if (!Element.prototype.setAttributeNodeNS) {
Element.prototype.setAttributeNodeNS = Element.prototype.setAttributeNode;
}

</code>

What line in the file?

The Line for adding is based on your error line in js file. In my case: it is the line

   _init: function(svgDocument){
        arguments.callee.$._init.apply(this, arguments);

        var svgNode = svgDocument.getElementsByTagName("g")[0]; //outer most g node
        // set all required attributes
//—> ADD HERE before error line
         if (!Document.prototype.createAttributeNS) {
     Document.prototype.createAttributeNS = function(namespaceURI, qualifiedName) {
       var dummy = this.createElement('dummy');
       dummy.setAttributeNS(namespaceURI, qualifiedName, '');
       var attr = dummy.attributes[0];
       dummy.removeAttributeNode(attr);
       return attr;
     };
   }
   if (!Element.prototype.setAttributeNodeNS) {
     Element.prototype.setAttributeNodeNS = Element.prototype.setAttributeNode;
   }
// —-> END ADD HERE
        var attributeTitle = svgDocument.ownerDocument.createAttributeNS(null, "title"); // <—– ERROR HERE (createAttributeNS)
        attributeTitle.nodeValue = this.getStencil().title();
        svgNode.setAttributeNode(attributeTitle);

@dqvn: Thank you very much for this information. I can confirm this: Adding the code

<code>
if (!Document.prototype.createAttributeNS) {
Document.prototype.createAttributeNS = function(namespaceURI, qualifiedName) {
    var dummy = this.createElement('dummy');
    dummy.setAttributeNS(namespaceURI, qualifiedName, '');
    var attr = dummy.attributes[0];
    dummy.removeAttributeNode(attr);
    return attr;
};
}
if (!Element.prototype.setAttributeNodeNS) {
Element.prototype.setAttributeNodeNS = Element.prototype.setAttributeNode;
}
</code>
BEFORE the line 15499 did the trick. Activiti developers, could you add this to the distro? The place where to add the code should be always on the same place in a way described by dqvn
